Roxy is multiplying 1/8 by 4/3

Vera_Pavlovna [14]

Answer:

1/6

Step-by-step explanation:

Make the denominators the same by finding the lcm(least common denominator). The least common demominator would be 24. So multiply both numbers in 1/8 by 3. This would eaqual 3/24. Multiply both numbersin 4/3 by 8. This would equal $\frac{3}{24} * \frac{32}{24}$ = $\frac{96}{576}$ . Simplify 96/576 by dividing both numbers by 96.
