Mass box A = 10 grams; Mass box B = 5 grams; Mass box C—made of one A and one B Mass ratio A/B =

LUCKY_DIMON [66]

Answer:

mass ratio of A/B is 2:1

Explanation:

Since the mass of box A = 10g

mass of box B = 5g

Mass of box C = mass of box A + mass of box

A ratio compares two quantities. To find the ratio of the two boxes:

Ratio of A to B = $\frac{mass of A}{mass of B}$

Ratio of A to B = $\frac{10grams}{5grams}$ = 2

The mass ratio is 2:1 i.e box A has twice the mass of B
