Answer:

The girls are 48 in number

Step-by-step explanation:

The question states that the ratio of boys to girls is 7 : 12, there are 76 children, we are to find the number of girls.

To find the number of girls, we are to follow the steps below;

Boys  :   Girls

 7       :   12

We take the ration number of girl which is 12 over the total ratio number then we multiply by 76.

The total ratio number = 7 + 12 = 19

That is;

 Number of girls = \frac{12}{19}  ×    76

                             =\frac{912}{19}

                             

                             =48

Therefore there are 48 number of girls

(02.05 MC) A dance school has 63 ballet dancers. If 42% of the total number of dancers in the school are ballet dancers, what is
Elena L [17]

Alright, lets get started.

Suppose total number of dancers in school = x

We have given in question, 42 % of total dancers are ballet dancers.

So, we could find number of ballet dancers by finding 42 % of total dancers.

Number of ballet dancers = x * 42 %

Number of ballet dancers = x * 42/100 = 0.42 x

As per given in question, there are 63 ballet dancers in school.

Which means 0.42 x = 63

Dividing 0.42 from both sides

0.42 x / 0.42 = 63 / 0.42

x = 150

Hence number of total dancers in school = 150 : Answer

Hope it will help :)
