Three-fourths of a number multiplied by seven

5 1/4 or 5.25

Step-by-step explanation:

Multiplying fractions means that we can multiply the numerator by the numerator and the denominator by the denominator straight across without needing a common denominator.

3*7 = 21

4*1 = 4

We end up with the improper fraction 21/4. We can convert this into a mixed number.

Because 4 goes into 21 a total of 5 times with 1 left over, we end up with the mixed number of 5 1/4, or as a decimal, 5.25
