Question

Harry HAS 1 1/2 KG whole-wheat flour. He uses 3/4 of the flour to bake bread. How much flour did he use?

Answer 1

`1(1)/(8)kg`

Explanations:

Given the following parameter

Mass of flour wheat flour = 1 1/2 kg

If Harry used 3/4 of these flour to bake bread, the amount of flour used is expressed as:

`A=(3)/(4)\text{ of 1}(1)/(2)`

Convert the mixed fraction into an improper fraction to have:

`\begin{gathered} A=(3)/(4)*(3)/(2)kg \\ A=(9)/(8)kg \\ A=1(1)/(8)kg \end{gathered}`

This shows that Harry used 1 1/8kg of the wheat flour to bake the bread
