To subtract fractions, you need a common denominator. In this case, the least common denominator is 20. Four tenths is equivalent to eight twentieths, and one fifth is equivalent to four twentieths. Therefore, eight twentieths minus four twentieths equals four twentieths, which can be simplified to two fifths.
Eight Fifths
3/10 minus 1/5 is 1/10.
It is: 3/10 = three tenths
2/5 minus 1/10 is 3/10.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
One fifth is two tenths. 8 tenths minus 2 tenths is 6 tenths or 3 fifths.

One half minus one fifth is 3 tenths
two tenths or, simplified, one fifth.

one fifth
7/10
No.
Eight Fifths
It would be two fifths turned into tenths which is two tenths - (when you turn fifths into tenths, you multiply it by 2 so you do the same with the numerator.) You do not change the denominator so you subtract the numerators 2-1=1. The answer is one tenth.
3/10 minus 1/5 is 1/10.
