Question

How do I multiply 12.8 x 3/4

Answer 1

You'll have to either transform 12.8 to a fraction or 3/4 to a decimal number. I'll transform 3/4 to a decimal:

3/4 = 0,75

After that we do the multiplication normally:

12.8 x 0,75 = 9,6

If you want, you can tranform 9,6 into a fraction:

$\frac{96}{10}$ = $\frac{48}{5}$

Answer 2

First, you have to make them alike by either turning them both into decimals or both into fractions. In this situation, it’s MUCH easier to turn the numbers both into decimals. 3/4 in decimal for is .75 which then allows you to multiply them!
