Question

write (90 sec to 7 min) as a ratio in its simplest form​

Answer 1

Answer:

3/14

Step-by-step explanation:

60 sec = 1 min

so we have:

$\frac{90 \: sec}{7 \: min} = \frac{90 \: sec}{7 \times 60 \: sec} = \frac{90}{420} = \frac{9}{42} = \frac{3}{14}$

Answer 2

Answer:

1.5:7

Step-by-step explanation:

To write an ratio, we need to understand what our problem is asking:

Given:

• 90 seconds to 7 minutes.

90 seconds to 7 minutes represents 1.5:7 as a ratio. (1.5 minutes to 7 minutes)

Simplifying a ratio means divide both sides by a whole number, there is no need to simplify this ratio, because the terms are already simplified to lowest terms.
