Question. Find the ratio between the days of May month to days in a particular year.

Given: Days in May to days in a year.

To find: We have to find the ratio between the days of May month to days in a particular year.

Just find out the number of days present in May month.

Then find the number of days in a year.

Then divide the days of May month by days in a year to get the ratio.

The May month consists of 31 days.

and in a year, there are usually 365 days.

Now if we divide these days, we get

Ratio = \(\frac{31}{365}\)

Ratio = 31 : 365

 

The ratio between the days of May month to days in a particular year is 31:365.

Question. Find the ratio between the numbers of sides of a triangle to the number of sides a square.

Given: Sides of a triangle to sides of a square.

To find: We have to find the ratio between the number of sides of a triangle to the number of sides a square has.

Just find out the number of sides of a triangle.

Then find the number of sides of a square.

Then divide them to find the ratio.

As we know, any triangle has “3” sides.

and any square always has “4” sides.

Now let’s take the division of the number of sides of a triangle and the number of sides of a square, we get the ratio as,

Ratio = \(\frac{3}{4}\)

Ratio = 3 : 4

 

The ratio of the sides of a triangle to the sides of a square is 3:4.

Question. Find the ratio between 8 triangles to 12 circles.

Given: There are 8 triangles and 12 circles are given.

To find: We have to find the ratio between 8 triangles to 12 circles.

Take division of them.

Then simplify them to obtain different ratios.

We have given 8 triangles and 12 circles.

The ratio for the above statement is   8/12  i.e. 8:12.

Dividing the ratio 8:12 i.e. 8 by 12 by 4 in both numerator and denominator, we get,

\(\frac{\frac{8}{4}}{\frac{12}{4}}=\frac{2}{3}\)

i.e. the ratio is 2:3.

Dividing the ratio 8:12 i.e. 8 by12 by 2 in both numerator and denominator, we get

\(\frac{\frac{8}{2}}{\frac{12}{2}}=\frac{4}{6}\)

i.e. the ratio is 4:6.

Multiplying the ratio 8:12 i.e. 8 by12 by 2 in both numerator and denominator, we get

\(\frac{8}{12} \times \frac{2}{2}\),

= \(\frac{16}{24}\)

i.e. the ratio is 16:24.

The three equivalent ratios of 8 triangles and 12 circles are,

​2 : 3

4 : 6

16 : 24

Question. Find the three equivalent ratios between 20 pencils and 25 erasers.

Given: There are 20 pencils and 25 erasers are given.

To find: We have to find the three equivalent ratios between 20 pencils and 25 erasers.

Take division of them.

Then simplify them to obtain different ratios.

We have been given 20 pencils and 25 erasers.

The ratio for the above statement is 20:25.

If we multiply and divide the numerator and denominator of the ratio 20/25 by “2”, we get

Ratio ​=20

= \(\frac{20}{25} \times \frac{2}{2}\)

= \(\frac{40}{50}\)

= 40 : 50

 

Dividing the ratio  40/50, by 10 in both the numerator and denominator, we get

\(\frac{\frac{40}{10}}{\frac{50}{10}}=\frac{4}{5}\)

i.e. the ratio is 4:5.

Dividing the ratio  40/50, by 5 in both the numerator and denominator, we get

\(\frac{\frac{40}{5}}{\frac{50}{5}}=\frac{8}{10}\)

i.e. the ratio is 8:10.

Three equivalent ratios of 20 pencils and 25 erasers are

​40 : 50

4 : 5

8 : 10

Question. Find the three equivalent ratios between 5 girls and 6 boys.

To find: There are 5 girls and 6 boys are given.

To find: We have to find the three equivalent ratios between 5 girls and 6 boys.

Take division of them.

Then simplify them to obtain different ratios.

We have given 5 girls and 6 boys.

Now divide them to get the different ratios.

Now let’s divide the number of girls and the number of boys, we get

= \(\frac{5}{6}\)

Ratio = 5 : 6

Now if we multiply and divide this ratio by “2”, we get

\(\frac{5}{6} \times \frac{2}{2}\)

= \(\frac{10}{12}\)

Ratio  = 10 : 12

Now if we multiply and divide this ratio by “3”, we get

\(\frac{15}{18}\)

Ratio = 15 : 18

Three equivalent ratios of 5 girls and 6 boys are,

​⇒ 5 : 6
⇒ 10 : 12
⇒ 15 : 18

Question. Find the three equivalent ratios between 10 pants and 14 shirts.

Given: There are 10 pairs of pants and 14 shirts given.

To find: We have to find the three equivalent ratios between 10 pants and 14 shirts.

Take division of them.

Then simplify them to obtain different ratios.

We have given 10 pairs of pants and 14 shirts.

The ratio is expressed as 10:14.

If we multiply the numerator and denominator by “2”, we get

= \(\frac{10}{14} \times \frac{2}{2}\)

= \(\frac{20}{28}\)

Ratio = 20 : 28 ​

The ratio obtained after the simplification of 20:28 is determined by dividing the numerator and denominator of 20/28 by 4, thus, we obtain

\(\frac{20}{28}\)

= \(\frac{5}{7}\)

i.e. the ratio is 5:7

The ratio 10:14, i.e. 10 by 14 is multiplied by 3 in both the numerator and denominator.

We obtain

\(\frac{10}{14} \times \frac{3}{3},\)

= \(\frac{30}{42}\)

i.e. the ratio is 30:42.

Three equivalent ratios of10 pants and14 shirts are,

​20 : 28

5 : 7

30 : 42
