Question

A baker needs 4 3⁄4 cups of flour. If she uses a 1 1⁄2 cup measuring scoop, how many scoops of flour must the baker use to have at least 4 3⁄4 cups?

Answer 1

Four. 1 1/2 + 1 1/2 = 3, + 1/12 = 4 1/2. But she still needs a fourth, so she'll need to use another scoop, so four.

Answer 2

`3(1)/(6)`

Explanation:

Given : A baker needs cups of flour =
`4(3)/(4) =(19)/(4)`

Solution :

Since we are given that she uses 1 measuring scoop for cup of flour =
`1(1)/(2) =(3)/(2)`

She uses uses scoop for 1 cup of flour =
`(1)/((3)/(2))=(2)/(3)`

She uses scoops for
`(19)/(4)` cups of flour =
`(2)/(3)*(19)/(4)`

=
`(19)/(6)`

=
`3(1)/(6)`

Thus
`3(1)/(6)` scoops of flour must the baker use to have at least 4 3⁄4 cups.
