Elsa's pumpkin weighs pound. Her pumpkin is 2/4 * 1/4 pound heavier than Carson's pumpkin. Elsa thinks that Carson's pumpkin must weigh 3/4 pound. How can Elsa correct her mistake?

The mistake you are referring to is not clear in the statement.

It is a statement which only describe the weighs of Elsa's and Carson's pumpkins.

Elsa's pumpkin weighs 7/8 Pounds, while Carson's pumpkin weights 3/4 Pounds.

Step-by-step explanation:

Given that Elsa's pumpkin is 2/4 * 1/4 pound heavier than Carson's pumpkin, and Elsa thinks that Carson's pumpkin must weigh 3/4 pound.

Simplifying the weigh of her own pumpkin,

Elsa: 2/4 * 1/4 = 2/16 = 1/8 Pounds

Carson: 3/4 Pounds

Elsa's weigh should then be

3/4 + 1/8 = 7/8 Pounds.
