Mr. santos has 3/4 of paint and each chair requires 1/9 of a gallon of paint. He thinks he has enough paint for 7 chairs.is he correct or incorrect

Start by determining how much paint is needed for the 7 chairs, that is 7 x 1/9. Then check if 3/4 is smaller or bigger then the amount needed for 7 chairs)

(3/4)gal / (1/9)gal/chair = 3/4 * 9/1 = 27/4 = 6 3/4 Chairs.

Incorrect: He is 1/4 gal. short.

Thanks

To determine if Mr. Santos has enough paint for 7 chairs, you need to compare the amount of paint he has with the amount needed for each chair.

First, let's calculate the total amount of paint Mr. Santos has. He has 3/4 of a gallon of paint.

Next, we need to calculate the amount of paint required for each chair. Each chair requires 1/9 of a gallon of paint.

To find out how many chairs can be painted with the amount of paint available, we divide the total amount of paint by the amount required for each chair. So, we divide 3/4 by 1/9.

In division, we invert and multiply the divisor. Therefore, we multiply 3/4 by the reciprocal of 1/9, which is 9/1.

(3/4) x (9/1) = (27/4)

This result, 27/4, represents the number of chairs that can be painted with 3/4 of a gallon of paint. However, it's not a whole number, so it means only a fraction of a chair can be painted.

To find the exact number of chairs that can be painted, we divide the numerator (27) by the denominator (4). This gives us 6 with a remainder of 3.

Therefore, Mr. Santos can paint 6 whole chairs completely with 3/4 of a gallon of paint, but he will have a paint remaining for 3/4 of a chair.

So, he is incorrect in assuming he has enough paint for 7 chairs. He actually has enough paint for 6 whole chairs and a little extra.
