Answer 2

Answer: 24 teachers

Step-by-step explanation:

The ratio of children to teacher is 35 : 6 or $\frac{35}{6}$. To find how many teachers is needed for 140 children, you would need to use the following equation:

$\frac{35}{6} = \frac{140}{x}$.

To solve this, you would need to cross multiply.

$\frac{35}{6} = \frac{140}{x}$

35 * x = (140) * (6)

35x = 840

$\frac{35x}{35} =\frac{840}{35}$            Divide both sides by 35

x = 24

Another way to do it:

$\frac{35}{6} = \frac{140}{x}$

$\frac{35x}{6} = 140$           Multiply x to both sides

$35x = 840$          

x = 24                Divide both sides by 35
