Question

1 3/4 cups of flour for one batch but he wants to make 1 1/2 batches. How many more cups of flour will he need

Answer 1

`2(5)/(8) cups = 1(1)/(2)\ batches`

Explanation:

Given

`1(3)/(4) cups = 1\ batch`

Required

Number of cups for
`1(1)/(2)` batches

`1(3)/(4) cups = 1\ batch`

Multiply both sides by
`1(1)/(2)`

`1(1)/(2) * 1(3)/(4) cups = 1\ batch * 1(1)/(2)`

`1(1)/(2) * 1(3)/(4) cups = 1(1)/(2)\ batches`

Express fractions as improper fractions

`(3)/(2) * (7)/(4) cups = 1(1)/(2)\ batches`

`(21)/(8) cups = 1(1)/(2)\ batches`

Express fraction as improper fraction

`2(5)/(8) cups = 1(1)/(2)\ batches`
