Convert 2 hours to minutes Step by Step

Step by step

The question

Question: change 2 hours into minutes.

2 h = ? min

1 Find the link

1 hour is 60 minutes.

1 h = 60 min

2 Make the unit fraction

We want minutes, so minutes go on top.

We have hours, so hours go at the bottom.

Top and bottom are the same amount.

So the fraction is 1, and times 1 keeps the size.

60 min1 h = 1

Careful!

Not upside down.

Then the hours would not cross out.

Careful: not 2 h × 1 h60 min ✗

3 Multiply

We multiply 2 hours by the fraction.

2 h = 2 h × 60 min1 h

Hours on top and at the bottom cancel, like numbers.

Cross them out.

Minutes are left.

What is left: 2 times 60.

= 2 × 60 min

2 times 60 is 120.

So 2 hours is 120 minutes.

= 120 min

4 Check

Does it make sense?

Minutes are smaller than hours.

So we need more of them.

120 is more than 2.

Yes.

min smaller than h → more: 120 > 2

And back the other way: 120 divided by 60 = 2.

We get 2 hours again.

So the answer is right!

back: 120 ÷ 60 = 2

Let's look back.

First: find the link.

Then: make the unit fraction.

Then: multiply.

Last: check.
