Question

Lucy does the following problem incorrectly. Explain the error and redo the problem showing the correct answer. Lucy’s answer -1.25-(0.25)= -1

Answer 1

Answer:

-1.5

Step-by-step explanation:

-1.25 - (0.25)

1. Put the negative sign (-) in the parentheses

-1.25 - 0.25

2. Subtract the two numbers

-1.25 - 0.25 = -1.5

Lucy subtracted the two numbers instead of seeing that the 0.25 has to be negative as well.
