Page 9 Problem 11 Answer

Given :- 60 peoples are invited to a party .there are 24 cups in a package and 18 napkins in a package.

Find :- least number of packages of cups and napkins that can be bought if each party guest gets one cup and one napkin . Using multiple and factor concept and proceed .

Given,
Number of cups in a package=24

Number of napkins in a package =18

Let total number of package of cups and napkins respectively x & y

Equation of total cups bought =24×x

Equation of total napkin bought =18×y

Total people invited to the party =60

as party guest gets one cup and one napkin total cups and napkins required :- Total number of cups bought

​24×x≥60

x≥60

24 x≥2.5
​

Number of package should be an integer therefor x=3

Total number of napkins bought

​18×y≥60

y≥10

3 y≥3.3
​

Number of package should be an integer therefor y=3

Least number of packages of cups bought are 3 and napkins is 4

Page 9 Problem 12 Answer

Given :- Given 45 members in science club .caps come in package of 3 and the shirts come in package of 5

Find :- what is the least number of packages of caps and shirts . Using multiple and factor concept and proceed .

Given , Caps come in package of 3 and the shirts come in package of 5

Total number of member in science club =45

Let total number of packages of caps and shirts x & y respectively .

Equation of caps ordering =3×x

Equation of shirts ordering =y×5

If club members get one cap and one shirts then required caps and shirts package :- Total number of caps ordered

​3×x≥45

x=15

​Total number of shirts ordered

​5×y≥45

y=9
​

The least number of caps and shirts 15 & 9 respectively.

We need 15 packages of caps and 9 packages of shirts and that is least number of caps and shirts packages.

So we need to find here the LCM of 8 & 7 LCM of 8,7 =56

We need 7 packages of hot dogs and 8 packages of buns.

Page 9 Problem 14 Answer

Find to the question how are the GCF and the LCM alike and different .

GCF is the greatest common factor is the greatest real number shared between two integers .what makes this number a factor is that it is a whole,real number that two integers share- that is , when broken down to their lowest multiples,the largest integer that is shared between the two numbers is their greatest common factor.

And the other hand,the lowest common multiple is the integer shared by two numbers that can be divided by both number.

The biggest difference between the GCF and LCM is that one is based upon what can divide evenly into two numbers,while the other depends on what number shared between two integers can be divided by the two integers (LCM).
