Answer:
Explanation:
To add the amounts of paint used, we need to have a common unit of measurement. One way to do this is to express both amounts in terms of a fraction of a gallon. Let's start by expressing 1 gallon as a fraction of a gallon using fraction strips.
We can use a fraction strip with 8 equal parts to represent 1 gallon, so each part represents 1/8 of a gallon.
1 gallon = 8/8
|-------|
1/8 1/8
Now let's express the amount of tan paint Lindsey used in terms of this fraction. Since she used 1 gallon, which is the same as 8/8 of a gallon, we can represent this amount on the fraction strip as follows:
1 gallon = 8/8
|-------|
8/8 0/8
Next, let's express the amount of green paint Lindsey used in terms of this same fraction. She used 43 gallons, so we can represent this amount on the fraction strip as follows:
43 gallons = 344/8
|----------------|
8/8 8/8 ... 8/8 (43 times)
To add these two amounts, we can simply combine the fraction strips by stacking them on top of each other.
1 gallon = 8/8
|-------|
8/8 0/8
43 gallons = 344/8
|----------------|
8/8 8/8 ... 8/8 (43 times)
Total = 352/8
= 44
So Lindsey used a total of 44 gallons of paint.
