Answer:
75 girls
Step-by-step explanation:
[tex]\dfrac{5}{8} \ are\ girls[/tex]
[tex]\dfrac{8-5}{8}=\dfrac{3}{8} \ are \ boys[/tex]
Let the total children = x
[tex]\dfrac{3}{8} \ of \ x = 45\\\\\dfrac{3}{8}*x = 45\\\\x =45*\dfrac{8}{3}= 15 * 8\\[/tex]
x = 120 children
Number of girls = 120 - 45 = 75
