Kayla spent 2 2/5 hours on his math homework and 1 3/5 hours on science homework how much time did he spend on math an science homework? write exspressen and answer

Answer 1

To find the total time Kayla spent on math and science homework, we need to add the time she spent on each subject:

2 2/5 + 1 3/5

To add these fractions, we need to have a common denominator. In this case, the denominators are already the same (5).

So, we can add the numerators:

2 + 1 = 3

3/5 + 3/5 = 6/5

Now, we can simplify the fraction:

6/5 = 1 1/5

Therefore, Kayla spent a total of 1 1/5 hours on math and science homework.
