To solve 8/6 divided by 4/6,think "How many four-sixths are in eight-sixth. What is this answer? Can anyone tell me this answer
Marrrta [24]

Answer:

2

Step-by-step explanation:

Dividing by fractions is the same as multiplying by its reciprocal. So 8/6 divided by 4/6 is the same as 8/6 times 6/4

You can then solve this two ways.

1) Multiply like normal and simplify:

  (8/6)(6/4) = 48/24 = 2.

2) Since there is a 6 in both the numerator and denominator, they cancel each other out. This leaves you with:

  (8/1)(1/4). Multiply across like normal to get 8/4 = 2.
