Question

Find the ratio of each of the following in simplest form:

$1minute$ to $15seconds$

Answer 1

Given ratio is $1minute$ to $15seconds$

Convert the given ratio in same unit.

We know that,

$1minute=60seconds$

Therefore, $1minute$ to $15seconds$ $=$ $60seconds$ to $15seconds$

Also, $60seconds:15seconds=\frac{60seconds}{15seconds}=\frac{60}{15}$

Now simplest form of $\frac{60}{15}$ can be obtained by dividing both term by their HCF $15$

$\frac{60}{15}=\frac{{\displaystyle \frac{60}{15}}}{{\displaystyle \frac{15}{15}}}=\frac{4}{1}$

Hence, simplest form of $1minute$ to $15seconds$ is $4:1$
