Question

Find the ratio of 1 1/2 hours to 25 minutes.

Answer 1

Answer:

18 : 5

Step-by-step explanation:

$\text{Convert}\ 1\dfrac{1}{2}\ h\ \text{to minutes.}\\\\\text{We know:}\ 1\ h=60\ min.\ \text{Therefore}\ 1\dfrac{1}{2}\ h=\left(1\dfrac{1}{2}\right)(60\ min)=90\ min\\\\\left(1\dfrac{1}{2}\ h\right):\left(25\ min\right)=(90\ min):(25\ min)=\dfrac{90}{25}=\dfrac{90:5}{25:5}=\dfrac{18}{5}=18:5$

Step-by-step explanation:

1 1/2hrs = 90 mins

90 / 5 = 18

I'd say: 18 : 5??
