Students

There are 2/6 girls out of 1050 students at the school. Of these, 4/5 have another sibling. How many girls are in school? How many boys are in school? How many girls do not have a sibling?

Final Answer:

d =  350
c =  700
x =  70

Step-by-step explanation:

$$\begin{gathered} n=1050 \\ d=\frac{2}{6}\cdot n=\frac{2}{6}\cdot 1050=\frac{2\cdot 1050}{6}=\frac{2100}{6}=350 \end{gathered}$$

$c=n-d=1050-350=700$

$x=d-\frac{4}{5}\cdot d=350-\frac{4}{5}\cdot 350=70$
