Question

What is 15/4 x 13/4 x 12/4? please help

Answer 1

$\dfrac{15}{4} \times \dfrac{13}{4} \times \dfrac{12}{4} = \dfrac{15 \times 13 \times 12}{4 \times 4 \times 4}$

You will need to reduce the answer you get from that, since there are numbers that divide into both the numerator and denominator.  

Can you take it from there?

Answer 2

Answer:

585/16

Step-by-step explanation:

Assuming these are 3 separate fractions 15/4 and 13/4 and 12/4,

multiply all the numerators 15 x 13 x 12 = 2340

multiply all the denominators 4 x 4 x 4 = 64

This is your fraction answer

2340/64

You can reduce it by dividing numerator and denominator by 4

585/16
