Question

Which Fraction Is Larger
5/12 Or 4/21

Answer 1

5/12

Explanation:

a ) 5/12

= 5/12 times 100% = 125/3 = 42 % rounded of to the nearest whole number

= 42 %

b ) 4/21

= 4/21 times 100% = 400/21 = 19 % rounded of to the nearest whole number

= 19 %

• 5/12 = 42% = Larger fraction
• 4/21 = 19 %

Answer 2

5/12

Since demoninators aren't the same we have to find a number that both numbers can divide into, which will be 84

5/84 & 4/84

Now whatever we do to the top we do to the bottom and so on. So how many times did it take those numbers to reach 84?

5/12 took 7 times to reach 84 so it will now be 5x7 like how we times 12 7 times to reach 84: 35/84

It took a shorter time for 4/21 to reach 84 as it only took 4 times so we times 4 by 4 and we get 16/84

Now let's compare: 16/84 or 35/84? We can see the bigger one is the second one, which was originally 5/12 and that's how you get the answer!
