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
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.
To find out how much time Kayla spent on math and science homework, we need to add the time spent on each subject.
First, let's add the time spent on math and science homework separately:
Math homework: 2 2/5 hours
Science homework: 1 3/5 hours
To add the time, we need to convert the mixed fractions into a common fraction. Here's how to do it:
For the math homework:
2 + 2/5 = (2 * 5 + 2) / 5 = 12/5
For the science homework:
1 + 3/5 = (1 * 5 + 3) / 5 = 8/5
Now, let's add the fractions:
12/5 + 8/5 = (12 + 8) / 5 = 20/5
The fraction 20/5 can be simplified, as both numerator and denominator are divisible by 5:
20/5 = (20 ÷ 5) / (5 ÷ 5) = 4/1 = 4
So, Kayla spent a total of 4 hours on math and science homework.
Expressed as an equation, the answer is:
2 2/5 + 1 3/5 = 4 hours
To find the total time Kayla spent on math and science homework, add the time spent on math (2 2/5 hours) to the time spent on science (1 3/5 hours).
2 2/5 hours + 1 3/5 hours
First, let's convert the mixed fractions to improper fractions:
2 2/5 = (5 * 2 + 2) / 5 = 12/5
1 3/5 = (5 * 1 + 3) / 5 = 8/5
Now, add the fractions:
12/5 + 8/5 = (12 + 8) / 5 = 20/5
Simplify the fraction:
20/5 = (20 ÷ 5) / 1 = 4/1 = 4
Therefore, Kayla spent a total of 4 hours on math and science homework.
