9/10 minus 9/15 is 3/10
Nine tenths plus two fifths minus one fourth is equal to 1.05
6/10 or 3/5
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.
3.4 - 1.9 = 1.5 = 1 and 1/2
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.
4 and two fifths
Yes, because 1/4 + 1/4 = 1/2
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.
That is 0.566
9/10 minus 9/15 is 3/10
Nine tenths plus two fifths minus one fourth is equal to 1.05
