Since 4 is evenly separated by 20, we can multiply simply one term to gain a common denominator.

You are watching: Whats 3/4 of 20

Multiply 3 through 5, and also get 15, then us multiply 4 by 5 and also get 20.

*

So now our fountain look like this:

1
20
+15
20

Step 2

Since our platform match, us can include the numerators.

1 + 15 = 16

Now we have an answer.

16
20

Step 3

Last the all, we need to simplify the fraction, if possible. Have the right to it be reduced to a easier fraction?

To uncover out, we shot dividing that by 2...

Are both the numerator and also the denominator evenly divisible through 2? Yes! therefore we alleviate it:

16
20
÷ 2 =8
10

Now, shot the same number again.

Are both the numerator and also the denominator evenly divisible by 2? Yes! therefore we minimize it:

8
10
÷ 2 =4
5

Now, try the exact same number again.

Nope. Shot the following prime number, 3...

Nope. Shot the next prime number, 5...

No good. 5 is bigger than 4. Therefore we"re done reducing.

Congratulations! Here"s your last answer to 1/20 + 3/4
