The answer is 15 and 3 fourths. 21 times 3 equals 63 then you put the 4 from the three fourths underneath and reduce 63 fourths to 15 and three fourths. 4 divided by 63 is 15 with a remainder of 3 which leaves you with 15 and three fourths.
Five twenty-fourths

First we convert to the same type, which is twenty-fourths: 6 twenty-fourths + 9 twenty-fourths + 10 twenty-fourths = 25 twenty-fourths or 1 and 1 twenty-fourth.
Three fourths times two is one and a half so if you add three fourths to that you will get two and one fourth.
one and three fourths equals seven fourths. seven fourths times seven fourths is forty nine over sixteen (3 and 1/16)
five and one quarter
one over eight
3/8
If you multiply the fraction three-fourths by two you will get six-fourths. If you change that improper fraction to a mixed fraction you will get one and two-fourths. The two-fourths reduces to one-half. There fore three-fourths times two is one and a half.
