Rosa and her friends used 1 2/3 quart of paint on Monday and 1 3/4 quart of pain on Tuesday. How much paint will Rosa and her friends need on Wednesday?
Is the amount used on Wednesday proportional to the amount used the other two days?
To find out how much paint Rosa and her friends will need on Wednesday, we need to add the amounts of paint used on Monday and Tuesday.
On Monday, they used 1 2/3 quart of paint, which can be written as 5/3 quart.
On Tuesday, they used 1 3/4 quart of paint, which can be written as 7/4 quart.
To add these fractions, we need to find a common denominator. The least common denominator of 3 and 4 is 12.
So, we can rewrite both fractions with the denominator of 12:
5/3 quart = (5/3) * (4/4) = 20/12 quart
7/4 quart = (7/4) * (3/3) = 21/12 quart
Now we can add the fractions:
20/12 quart + 21/12 quart = (20 + 21)/12 quart = 41/12 quart
Finally, we can simplify the fraction if needed:
41/12 quart = 3 5/12 quart
So, Rosa and her friends will need 3 5/12 quart of paint on Wednesday.
