Question 1144144: Over the past week, 34 baby boys were born at the hospital. This was 54% of all babies born. How many girls were born over the past week? (Enter numeric value only. If rounding is necessary, round to the nearest whole number.) Answer by math_helper(2461) (Show Source):
Let G = number of girls
then the total number of babies born was G + 34, and we are given 54% (0.54) of that total is 34:
0.54(G + 34) = 34
Divide both sides by 0.54:
G+34 = (34/0.54)
Subtract 34 from each side:
G = (34/0.54) - 34 = 29 (after rounding)
Check:
34/ (34+29) = 34/63 = (approx) 0.5396 or 54% when rounded.
