Three 232

Three out of eleven working mothers in a major US city have at least one child under the age of Five(5). If there are 2,250 mothers employed in that city, how many have at least one child under the age of five? (round to nearest whole number)

Correct answer:

n =  614

Step-by-step explanation:

$$\begin{gathered} r=\frac{3}{11}\doteq 0.2727 \\ {n}_1=r\cdot 2250=\frac{3}{11}\cdot 2250=\frac{3\cdot 2250}{11}=\frac{6750}{11}\doteq 613.6364 \\ n=[n_1]=[613.6364]=614 \end{gathered}$$
