Question

Catherine studied 1.25 hours for her science test. This was 0.5 hours less than she studied for her algebra test. Write and solve a subtraction equation to find how long she studied for her algebra test.

Answer 1

1.25 - 0.5 = 0.75


1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes

1 hour 15 minutes - 30 minutes = 45 minutes
