Reginald answered at 78% of the questions on his social studies quiz correctly what fractional part of the question did he not answer correctly

If Reginald answered 78% correctly out of a total 100%, we can subtract 78 from 100:

100 - 78 = 22

He answered 22% of the question incorrectly. But how do we find the bottom number? Remember what we said earlier. The total is 100%. He got 22% out of 100% wrong. Wouldn't that be ?

Now that we know our fraction, we can reduce it. Let's start by dividing our fraction in half:

=

Can we reduce that any more? No, because 11 can not be divided by anything else.

If you want the first fraction, go with , but if they want a reduced fraction, then would be best.

step-by-step explanation:

distance=1 00 meters
