Question

40 minutes : 1 hour 40 minutes in the simplest form

​

Answer 1

2 : 5

Explanation:

We require the time to be in the same units

1 hour 40 minutes = 60 + 40 = 100 minutes , then

40 min : 100 min ( divide both parts by 20 min )

= 2 : 5

Answer 2

9514 1404 393

Answer:

2 : 5

Explanation:

You know an hour is 60 minutes, so 1 hour 40 minutes is 60+40 = 100 minutes. Then the ratio is ...

40 min : 1 h 40 min = 40 min : 100 min = 40 : 100 = 2 : 5

(a common factor of 20 can be removed from 40 and 100)
