Question

How would you solve 3/4 over 1/2 as a ratio

Answer 1

Answer:

  3/2

Step-by-step explanation:

A couple of different methods are used for dividing fractions.

1. "Invert and multiply". Dividing by a number is the same as multiplying by its reciprocal:

  (3/4) / (1/2) = (3/4) × (2/1)

  = (3·2)/(4·1) = 6/4 = 3/2

__

2. Make the denominators the same and use the ratio of numerators.

  (3/4) / (1/2) = (3/4) / (2/4) = 3/2

_____

For these fractions, you can recognize that 3/4 is 1/4 more than 1/2, and that 1/4 is half of 1/2. That means 3/4 is half-again as much as 1/2, so is 1 1/2 = 3/2 times 1/2. This tells you the ratio (3/4) : (1/2) = 3/2.

__

Along the lines of the above, you can write the ratio as ...

  (3/4) : (1/2)

and multiply by 4 to get

  = (3/4)×4 : (1/2)×4 = 3 : 2
