Eight Fifths
To subtract nine tenths and one fifth with a common denominator, first find the common denominator, which is 10. Convert one fifth to tenths: one fifth equals two tenths. Then, subtract: nine tenths minus two tenths equals seven tenths. So, nine tenths minus one fifth is seven tenths.
Nine tenths plus two fifths minus one fourth is equal to 1.05
Eight minus seven and nine tenths is equal to zero point one. This is calculated by converting eight to a decimal (8.0) and subtracting 7.9, resulting in 0.1.
9/10 - 2/3 = 7/30
3/5 also equals 6/10 or 6 tenths The answer is therefore 6 tenths minus 9 tenths = minus 3 tenths Assuming of course that these portions are from the same object/ number etc. you have 30% less than when you started.

Nine tenths plus two fifths minus one fourth is equal to 1.05
9/10 - 1/5 = 7/10
Nine tenths minus four tenths is five tenths, which is also a half.
