Question

For every 10 cups of coffee, 15 sugar cubes are used. The ratio of the number of sugar cubes to cups of coffee is

• A. 3:2
• B. 2:3
• C. 10:15

Answer 1

The correct option is A 3:2

$\text{Number of cups of coffee}=10$
$\text{Number of sugar cubes}=15$

$\text{Fractional representation of sugar cubes}\text{per cups of coffee}=\frac{15}{10}$

$\frac{15}{10}=\frac{15÷5}{10÷5}=\frac{3}{2}$

$\text{Representing the fraction as a ratio, we}\text{get:}$

$\frac{3}{2}⟹3:2$

So, from 3 sugar cubes, 2 cups of coffee can be made.

$\therefore \text{The ratio of the number of sugar}$ $\text{cubes to cups of coffee is 3:2}$
