Answer 1

1 hour 12 minutes x 3 = 3 hour(s) + 36 minute(s)

Explanation:

Given:

1 hour 12 minutes x 3 = .-----------hours -------------minute(s)

Solution:

1 Hour = 60 minutes

So you First add 60 to 12 minutes

i.e 72 minutes

Now 3 times 72 minutes = 3 × 72 = 216 minutes

60 minutes = 1 hour

216 minutes = 60 + 60 + 60 + 36

= 1 hour + 1 hour + 1 hour + 36 minutes

= 3 hour(s) + 36 minute(s)

∴ 1 hour 12 minutes x 3 = 3 hour(s) + 36 minute(s)
