Nine tenths minus four tenths is five tenths, which is also a half.
One fifth is two tenths. 8 tenths minus 2 tenths is 6 tenths or 3 fifths.
four tenths
It is minus one half.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.
9/10 minus 3 is -2 1/10
7/10 minus 5/10 is 1/5.
-2/10
3 tenths of course !
4 and 4 tenths...
To subtract fractions, we need a common denominator. The least common multiple of 10 and 15 is 30. So, we rewrite 9/10 as 27/30 and 4/15 as 8/30. Subtracting, we get 27/30 - 8/30 = 19/30. Therefore, 9/10 - 4/15 = 19/30.
