Question

Pizza chefs buy 5 5/8 kg of flour. They use 3/5 of the flour to make 9 equal mini pizzas. How much flour did they use for each mini pizza? Express your answer as a fraction in its lowest form.

Answer 1

Flour used to make 9 pizzas = 5
`(5)/(8)` ×
`(3)/(5)`

= 3
`(3)/(8)`

Flour used for each pizza = 3
`(3)/(8)` ÷ 9

= 3
`(3)/(8)` ×
`(1)/(9)` (reciprocal of 9)

=
`(3)/(8)`

The amount of flour used for each mini pizza is
`(3)/(8)` kg.
