Question

Find the ratio of $18$ seconds to $1$hours.

Answer 1

Step 1: To convert hours to seconds.

We know that, $1$hour $=$$60$ minutes

And $60$minutes $=60$ seconds

Hence, $1$hour $=(60\times 60)=3600$ seconds

Therefore, the ratio of $18$ seconds to $1$hours is the ratio of $18$ seconds to $3600$ seconds.

Step 2: To find the ratio.

The ratio of $18$seconds to $3600$seconds $=\frac{18}{3600}=\frac{18÷18}{3600÷18}=\frac{1}{200}=1:200$

Therefore, the ratio of $18$ seconds to $1$ hours is $1:200$
