Question

How many extra cats do we need to make the ratio of cats to dogs $2:3$?

• A. $2$
• B. $1$
• C. $3$
• D. $4$

Answer 1

The correct option is A $2$

We have to find the number of extra cats we need to make the ratio $2:3$.
The ratio $2:3$ can also be written as $4:6$ when both numbers are multiplied by $2$.

In the figure, we have $2$ cats and $6$ dogs
So, the ratio of cats to dogs is $2:6$.

To make the ratio $4:6$, we need $2$ more cats to make $4$ cats and $6$ dogs.
The new ratio $4:6$ in its simplest forms is $2:3$.
