3/8 minus 1/5 is 7/40
5 and 8/10 minus 3 and 1/2 = 2 and 3/10
Since LCM(4, 5, 10) = 20, 1/4 - 2/5 - 3/10 = 5/20 - 8/20 - 6/20 = -9/20
8 - 2 4/5 = 5 1/5
Call it 21 fifths minus 13 fifths, ie 8 fifths which is one-and-three-fifths
One fifth is two tenths. 8 tenths minus 2 tenths is 6 tenths or 3 fifths.
It is: 8/10 minus 2/5 = 2/5
7 fourths minus 8 fifths = -1
4/5 can also be written as 8/10, so therefore 9/10 - 8/10 = 1/10 (one tenth).
3/8 minus 1/5 is 7/40
eight tenths means 8 x 1/10 which = 8/10 = 4/5 = .80
8/10 = 4/5 If you divide both the 8 and the 10 by 2, the answer is four fifths. There are 4 fifths in eight tenths.
four fifths is equal to eight tenths 4/5 = 8/10
7/10 minus 1/6 is 8/15
5 and 8/10 minus 3 and 1/2 = 2 and 3/10
Since LCM(4, 5, 10) = 20, 1/4 - 2/5 - 3/10 = 5/20 - 8/20 - 6/20 = -9/20
42/5 - 16/10 = 42/5 - 13/5 = 22/5 - 8/5 = 14/5 = 24/5
