Question

5 by 8 of the children in the field are girls. There are 45 boys. How many girls are there?

Answer 1

Answer:

75 girls

Step-by-step explanation:

$\dfrac{5}{8} \ are\ girls$

$\dfrac{8-5}{8}=\dfrac{3}{8} \ are \ boys$

Let the total children = x

$\dfrac{3}{8} \ of \ x = 45\\\\\dfrac{3}{8}*x = 45\\\\x =45*\dfrac{8}{3}= 15 * 8$

x = 120 children

Number of girls = 120 - 45 = 75

Answer 2

5+8 = 13

5:8

8÷5 × 45
