Answer:
5 3/10
Explanation:
Forget your whole number for now and just work on the fractions.
Find the lowest common denominator to use so you can subtract the fractions.
Tenths is the lowest common denominator so convert your fractions that is in fifths to tenths.
3/5 = x/10 multiply the bottom and top by 2
2 x 3 = 6
------------- so 3/5 = 6/10
2 x 5 = 10
Subtract your whole numbers: 7 - 2 = 5
Subtract your fractions: 6/10 - 3/10 = 3/10
Answer is 5 3/10
