9/10 - 4/10 = 5/10 = 1/2.
To calculate nine tenths minus one seventh, first find a common denominator. The least common denominator of 10 and 7 is 70. Converting the fractions, nine tenths becomes 63/70 and one seventh becomes 10/70. Therefore, nine tenths minus one seventh is 63/70 - 10/70 = 53/70.
To solve nine tenths minus two fourths, first convert two fourths to a decimal or a fraction with a common denominator. Two fourths is equivalent to one half, which is 0.5 or 5 tenths. Therefore, nine tenths minus five tenths equals four tenths. Simplifying four tenths gives you two fifths.
Nine tenths minus four tenths is five tenths, which is also a half.
To subtract 8 fifteenths from 7 tenths, first convert both fractions to have a common denominator. The least common multiple of 10 and 15 is 30. Converting, 7 tenths becomes 21 thirtieths (7/10 = 21/30), and 8 fifteenths becomes 16 thirtieths (8/15 = 16/30). Therefore, 21/30 - 16/30 equals 5/30, which simplifies to 1/6.
One fifth is two tenths. 8 tenths minus 2 tenths is 6 tenths or 3 fifths.
four tenths
It is minus one half.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
7/10 minus 5/10 is 1/5.
9/10 minus 3 is -2 1/10
Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.
3 tenths of course !
