A leaky pool loses 2 and one-fourth inches of water each day. Jermaine and Mildred are asked to determine the change in the amount of water in the pool over 5 days.
Jermaine’s Solution
Mildred’s Solution
5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth) = negative 10 minus one-fourth = negative 10 and one-fourth
5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth) = negative 10 minus StartFraction 5 over 4 EndFraction = negative 11 and one-fourth
Which describes the reasoning used to determine whose solution is correct?
Jermaine is correct because Negative 10 minus one-fourth equals Negative 10 and one-fourth
Jermaine is correct because he distributed 5 correctly.
Mildred is correct because she multiplied 5 by –2 but not by Negative one-fourth.
Mildred is correct because she distributed 5 correctly.
