In one hour, Ed used 2/5 of time to complete his homework and 1/4 of the time to check his email. How much time did he spend completing homework and checking email? Write answer as a fraction
8/20 + 5/20 = 13/20
To find the total amount of time Ed spent completing his homework and checking his email, we need to add the fractions 2/5 and 1/4.
First, we need to find a common denominator for the fractions 5 and 4. The least common multiple of 5 and 4 is 20.
Next, we need to rewrite the fractions with the common denominator of 20.
For 2/5, we can multiply both the numerator and the denominator by 4 to get 8/20.
For 1/4, we can multiply both the numerator and the denominator by 5 to get 5/20.
Now, we can add the fractions together:
8/20 + 5/20 = 13/20
Therefore, Ed spent 13/20 of the hour completing his homework and checking his email.
