### Question 22

Taj has three scoops for measuring flour. The largest scoop holds 2 1/2 times as much as the smallest one. The middle scoop holds 1 3/4 times as much as the smallest one.

Describe two different ways in which Taj could measure each of the following quantities. He can use full scoops only.

a) 3 1/4 times as much as the smallest scoop holds.

First off, i figured that the smallest scoop is 1, or 1/1.

To get 3 1/4 as much as the smallest scoop, I changed the fractions into decimals, so i ended up with

large scoop:2.5

medium scoop:1.75

small scoop:1.0

I then changed 3 1/4 to a decimal and got 3.25.

The two answers I came up with were:

1.large scoop (2.5) + medium scoop (1.75) - small scoop (1.0) = 3.25

2.two large scoops (5) - medium scoop (1.75) = 3.25

b)1/2 as much as the smallest scoop holds.

1.two large scoops (5) - two medium scoops (3.5) - one small scoop (1.0) = 0.5

2.two medium scoops (3.5) - three small scoops (3) = 0.5

if u have ne suggestions plz comment
