1 2/5
4/5 plus 2/10 = 1
3/10 + 1/5 = 1/2
It is the same as: 1/5+2/5 = 3/5
2.7 + 2.8 = 5.5 = 5 and 1/2
The sum of 9/10 and 3/5 is 1 1/2 or 1.5
It is: 3/10+3/5+1/2 = 7/5 or 1.4 as a decimal
6 tenths 2/5 = 4/10 2/10 + 4/10 = 6/10
Three-fifths (3/5) minus two-tenths (2/10) can be calculated by first converting two-tenths to fifths. Since 2/10 is equivalent to 1/5, we can rewrite the expression as 3/5 - 1/5. This simplifies to 2/5. Therefore, three-fifths minus two-tenths equals two-fifths (2/5).
3.8 + 2.9 = 6.7
It works out at 9 tenths, or 0.9 in decimal.
