Given: It is given that the four friends equally shared the cost of supplies for a picnic. The total cost of supplies is $12.40

To find: We have to find how much money each friend paid.We will find the money each person paid by dividing the total cost by four.

Firstly, we will remove the decimal point from the denominator of the division expression by multiplying both the denominator and numerator by 10.

We have, 12.4/4 = 124/40

The division of the given cost by four is

Given: It is given that Kesha spent a total of$9.60 on new shoelaces and each pair costs $1.20

To find: We have to find how many pairs did she buy. We will divide the total cost by the cost of one pair.

The pairs of shoelaces that she bought are ​9.60/1.20=96/12 =8
​
The total number of pairs of shoelaces that Kesha bought is 8

Given: It is given that one inch equals 1/4

hand and average Clydesdale is 17×1/5 hands tall. To find: We have to find the height of the horse in inches and in feet.

We will convert the height of Clydesdale in inches with the help of the given relation and then convert it into feet.

We will convert mixed fractions into improper fractions. The height of Clydesdale is 17×1/5=86/5

We will convert this height in hands into height in inches. We get, 86/5×1/4=4.3in

Now, the height in feet is 4.3×1/12=0.3583ft

The height of the horse in inches is 4.3in

The height of the horse in feet is 0.3583ft

Given: It is given that the banana bread recipe contains 3/4

cup of butter and one tablespoon equals 1/16 cup. To find: We have to find the number of tablespoons of butter needed.

We will divide the total cup of butter required by the butter that one tablespoon contains.

As we want to divide the fractions, we will rewrite the division as multiplication by reciprocating the divisor. We get, 3/4×16=12

The number of tablespoons needed is 12

Given: It is given that Cindy earns $5.75 per hour. She works 12.4 hours per week. She worked50 weeks in a year.

To find: We have to find how much she earned in a year. We will find this by multiplying the pay per hour by the total number of hours per year.

We will first calculate the total number of hours in a year.

We get,12.4×50=620 The total income that she earned in a year is 5.75×620=3565

The total earnings of Cindy per year are$3565

Given: Joey scored 9.4,9.7,9.9,9.8 and Carlos scored 9.5,9.2,9.7,9.6

To find who’s average is high. Using the method of average.

To find the average of Joey’s score average = sum of all the numbers / Total numbers

Now to find the average for Carlos’s score,

Given: granola recipe calls for2x1/3

cup of almonds. A bag of almonds contains 2 cups. Ali buys 5 bags of almonds. To find how many cups of almonds will he have left over.

Using the method of multiplication. It is given that a granola recipe calls for 21/3

cups of almonds, each bag of almonds contain2 cups, Ali will make 21/2 batches of granola, and he bought 5bags of almonds.

First, we need to find how many cups of almonds he needs by multiplying the number of cups in each batch and the number of batches he will make,

=2×1/2×2×1/3=35/6  write in mixed fractions,

=5×5/6

To find how many cups are left, we can then subtract the number of cups he bought and the total number of cups he needs,

=10−5×5/6 simplify, = 4×1/6

There are 4×1/6 cups of almonds are left over.

Next, we need to find how many cups he bought by multiplying the number of cups in each bag and the number of bags he bought. He the bought2×5=10 cups of almonds.

Given: three pandas eat a total of 181×1/2 pounds of bamboo shoot each day.

The male panda eats 3 times as much as the baby and the female panda eats 2 times as much as the baby.

To find how many pounds does the female panda eats. Using the method of division.

It is given that 3 pandas at a zoo each a total of 181×1/2 pounds of bamboo each day, the male eats 3 times as much as the baby, and the female eats 2 times as much as the baby.

Using the given information, we then get the ratio, male: female: baby=3:2:1

To find how much the female panda eats, we first need to write the ratio of females: all 3 pandas.

Since3+2+1=6, then the ratio is,female: all 3 pandas = 2:6

Reducing this ratio by dividing both numbers by 2 gives: female: all3 pandas2:6=2/6 simplify, =1/3

Now we need to write an equivalent ratio that has 181×1/2 = 363/2 as the second number in the ratio.

The female panda eats 60×1/2 pounds of the bamboo shoot aday.

Given: Jan has $37.50 and the cost of one ticket is $5.25

To find how many tickets can Jan buy with the amount he has.Using the method of division.

Jan has $37.50 and the cost of one ticket is $5.25  to find how many tickets can he buy with the amount he has, here we should divide the total amount by the cost of one ticket because we are going to find the number of tickets can buy with the total amount so division takes place here.

Now divide the total amount by the cost of one ticket,

Given: Jon has $45.00 and he plans to spend 4/3 of his money on sports equipment.To find how much will he spend.Using the method of multiplication.

It is given that Jon has $ 45 and plans to spend 4/5 of his money on sports equipment.

Go Math! Practice Fluency Workbook Grade 6, California 1st Edition, Chapter 5 Operations with Decimals e2

Since we know the total amount of money he has and what fraction of the total he will spend on sports equipment, we need to multiply to find how much he will spend.

Given: Ricki has $ 76.8 feet of cable. She plans to cut it into 7 pieces.To find the length of each cable. Using the method of division.

It is given that Ricki has 76.8 feet of cable and will cut it into 7 pieces.

Since we know the total length and how many pieces it will be cut into, we need to divide to find the length of each piece.

Dividing 76.8 and 7 up to 3 decimal place gives = 76.8/7 divide, =10.971

Go Math! Practice Fluency Workbook Grade 6, California 1st Edition, Chapter 5 Operations with Decimals e4

Rounding to the nearest hundredth gives 10.97 so each piece will be about 10.97ft.

The length of the cable is 10.97 ft long.
