8 9/10 - 6 1/10 = 8.9 - 6.1 = 2.8
1 tenth
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.
Eight Fifths
It is seventy-eight and nine tenths.
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.
1 tenth
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.
Eight Fifths
Nine tenths minus four tenths is five tenths, which is also a half.
To subtract fractions, you need a common denominator. In this case, the common denominator for 10 and 15 is 30. Therefore, nine tenths is equivalent to 27 thirtieths, and eight fifteenths is equivalent to 16 thirtieths. Subtracting 16 from 27 gives you 11 thirtieths. Therefore, nine tenths minus eight fifteenths is equal to 11/30.
9/10 - 1/2 = 9/10 - 5/10 = 4/10 = 2/5.Or, 0.9 - 0.5 = 0.4.Nine tenths minus one half is four tenths.
The sum of (eight and nine tenths) plus (nine and eight tenths) is (eighteen and seven tenths). 8.9 + 9.8 = 18.7
The answer is 27.6. The sum is 8+12.1+6.6+.9
7 3/10 - 4 4/10 = 2 9/10, or two and nine tenths.
It is seventy-eight and nine tenths.
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.
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.
