Answer:
Girls (Morning) = 16
Step-by-step explanation:
<em>60 children go to a nursery. The ratio of girls to boys is 3 : 2</em>
Number of Boys = 3 / (3 + 2) * 60 = 3/5 * 60 =36
Number of Girls = 2 / (3 + 2) * 60 = 2/5 * 60 = 24
<em>Three quarters of the children go to the nursery in the morning.</em>
Number of children (Boys + Girls) = 3/4 * 60 = 45
<em>The rest of the children go to the nursery in the afternoon.</em>
Number of children (Boys + Girls) = 60 - 45 = 15
<em>7 boys go to the nursery in the afternoon.</em>
Boys + Girls = 15
Girls (Afternoon) = 15 - Boys = 15 - 7 = 8
<em>Work out how many girls go to the nursery in the morning.</em>
Girls (Morning) + Girls (Afternoon) = Girls (Total)
Girls (Morning) + 8 = 24
Girls (Morning) = 24 - 8
Girls (Morning) = 16
