Answer:

The sum of two-fifths and f is 1/2 can be represented by:

2/5+f=1/2

Then to solve for f an easier way would be turn the fractions into decimals to get:

0.4+f=0.5 (subtract 0.4 from both sides)

f=0.1 or 1/10

hope this helps mark brainliest if it does :)

Answer:

1/10

Step-by-step explanation:

2/5 + f = 1/2

subtract two fifths from both sides

f = 1/10
