Rosa and her friends used 1 2/3 quart of paint on Monday and 1 3/4 quart of pain on Tuesday. If Rosa and her friends have 3/4 quart of paint left, do they have enough paint to finish the job on Wednsday?

no idea. How much does it take (x qts) to do the whole job? Whatever that is, do you have

1 2/3 + 1 3/4 + 3/4 >= x
??

To determine if Rosa and her friends have enough paint to finish the job on Wednesday, we need to find the total amount of paint they used on Monday and Tuesday, and then subtract that from the initial amount of paint they had.

On Monday, they used 1 2/3 quart of paint, which can be written as 5/3 quarts (since 1 and 2/3 is equivalent to 5/3).

On Tuesday, they used 1 3/4 quart of paint, which can be written as 7/4 quarts (since 1 and 3/4 is equivalent to 7/4).

So, the total amount of paint used on Monday and Tuesday is 5/3 + 7/4.

To add these fractions, we need to find a common denominator, which is 12 in this case. So, we convert 5/3 to twelfths by multiplying the numerator and denominator by 4, which gives us 20/12. Similarly, we convert 7/4 to twelfths by multiplying the numerator and denominator by 3, which gives us 21/12.

Now, we can add the two fractions: 20/12 + 21/12 = 41/12.

So, Rosa and her friends used a total of 41/12 quarts of paint on Monday and Tuesday.

If they started with 3/4 quart of paint and used 41/12 quarts, we need to subtract the amount used from the initial amount to find out how much is left.

To subtract fractions, we need a common denominator. The common denominator here is also 12.

So, we can write 3/4 as 9/12.

Subtracting 41/12 from 9/12, we get: 9/12 - 41/12 = -32/12.

The result is a negative fraction, which means they used more paint than they had. They do not have enough paint to finish the job on Wednesday.

In conclusion, based on the given information, Rosa and her friends do not have enough paint to finish the job on Wednesday.
