If jamie walks 1/2 a mile in 1/4 of an hour, how
many miles can jamie walk in one hour?

The number of miles Jamie can walk in one hour is 2 miles

Given:

Number of miles Jamie walks = 1/2 mile

Time taken to walk = 1/4 hour

Ratio of miles Jamie walks to ratio of time taken = 1/2 : 1/4

If Jamie walks for 1 hour

let

x = number of miles walked

Ratio of miles Jamie walks to ratio of time taken = x : 1

Equate the ratio

1/2 : 1/4 = x : 1

1/2 ÷ 1/4 = x / 1

1/2 × 4/1 = x / 1

(1 × 4) / (2 × 1) = x / 1

4 / 2 = x / 1

cross product

4 × 1 = 2 × x

4 = 2x

divide both sides by 2

x = 4/2

x = 2 miles

Therefore, the number of miles Jamie can walk in one hour is 2 miles.

1/4 / 1/2 = ?

First of all, you can see we need to divide 1/2 by 1/4.

But we need to be careful what we need to do :)!

Others predict the answer is 2 miles and I really think so too. So I going to show you every step of this problem so we get it correct, sounds good? :)

So Jamie walks 1/2 a mile in 15 minuets, we cannot divide 15 and 1/2, so we would stick with 1/4.

Next, before we multiply, we need to know how to “Cross Reduce” Cross reducing is finding the greatest common factor of 2 fractions by opposite numerators and opposite denominators.

I will give an example in comments with picture. :D

Now we will divide, when we cross reduce, the fractions look like 1/4 and 1/2, there was nothing to reduce.

So 1/2 divided by 1/4 equals 2 miles.

So everyone that said 2 miles, amazing job!! We are all correct and the final answer is 2 miles.

Therefore, we learned how to Cross Reduce, divide fractions, and learn how to divide fractions.

To sum up the basics, for more information you should ask your teacher yet one classmate to be very sure.

Stay and have a great night. :)
