There are 34 Pre-K children and 29 kinder garden children on the playground, some boys and some girls. The ratio of boys to girl

Natali [406]

There are 27 boys on the playground.

Step-by-step explanation:

No. of Pre-K children = 34

No. of kindergarten children = 29

Total no of children = 29+34 = 63

Ratio of boys to girls = 3:4

Total ratio = 3+4 = 7

Therefore,

boys proportion = $\frac{3}{7}$

Total number of boys = $\frac{3}{7}\ of\ total\ number\ of\ children$

$Total\ number\ of\ boys = \frac{3}{7} *63\\Total\ number\ of\ boys = \frac{189}{7} \\Total\ number\ of\ boys = 27$

There are 27 boys on the playground.
