Question

Bjorn is making aush, and he does not have enough of all the ingredients. He decides to make 5/6 of a whole recipe, which means he uses 1 1/4 L of water.

How much water is in a whole recipe?
____?

Answer 1

If Bjorn used 5/6 of the whole recipe to make 1 1/4 L of water, we can find out how much water is in the whole recipe by using a proportion:

5/6 of the whole recipe = 1 1/4 L of water
1 whole recipe = (1 1/4 L of water) / (5/6)
To divide a fraction by another fraction, we can multiply by the reciprocal of the divisor. Therefore, we can simplify the above expression as follows:

1 whole recipe = (1 1/4 L of water) * (6/5)
Multiplying 1 1/4 L by 6/5, we get:

1 whole recipe = (5/4 L) * (6/5) = 30/20 L = 1 1/2 L
Therefore, a whole recipe of aush requires 1 1/2 L of water.

Answer: 1 1/2 L
