Answer:

7.5 litres: 15 litres = 15 children: 30 children

We can verify it by keeping them in proportion.

Let us verify-

Left Hand Side                  Right Hand Side      

7.5 Litres: 15 Litres  :  :  15 children: 30 children

7.5 Litres / 15 Litres =  15 children/ 30 children

$\frac{7.5 L}{15 L} =\frac{15}{30} children$

$\frac{75}{15 * 10}Litres = \frac{15}{30} children$

75/150 L = 15/30 children

$\frac{75}{150} L =\frac{15}{30} children$

75 * 30 = 150 * 15

2250 = 2250

LHS = RHS

Hence verified ........................

You can also convert $\frac{75}{150}L$ and $\frac{15}{30}$ children in their simpler form which would be 1/2 and1/2 respectively and apply every step after that)
