[tex]\dfrac{15}{4} \times \dfrac{13}{4} \times \dfrac{12}{4} = \dfrac{15 \times 13 \times 12}{4 \times 4 \times 4}[/tex]
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:
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
