To find out how long it took Liwanu to do both his math and science homework, we need to add the time taken for each subject.
The time taken for math homework is 2/25 hours.
The time taken for science homework is 1 3/5 hours, which can be written as (5/5 + 3/5) = 8/5 hours.
To find the total time taken, we add these two times: 2/25 + 8/5.
To add these fractions, we need a common denominator, which is 25 in this case.
Converting the second fraction to have a denominator of 25: 8/5 = (8/5) * (5/5) = 40/25.
Now we can add the fractions: 2/25 + 40/25 = 42/25.
The total time taken to do science and math homework is 42/25 hours.
Alternatively, we can simplify this fraction by dividing the numerator and denominator by their greatest common divisor, which is 1: 42/25 = 42 ÷ 1 / 25 ÷ 1 = 42/25.
Therefore, it took Liwanu 42/25 hours to do both his math and science homework.
liwanu spent 2/25 hours on his math homework and 1 3/5 hour on his science homework. how long did it take him to do science and math homework
