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
