To subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are subtracted and the resulting fraction simplified:
9/18 - 3/9 = 9/18 - 6/18
= 3/18
= 1/6
3 minus 3/18 is 2 5/6
3/18
1 over 2
14/20 minus 3/5 is 1/10
17/18 - 2/3 = 17/18 - 12/18 = 5/18
14
0.27
It is -25/36
17/18
it is 2 over 4
No. 18/27 is equal to 2/3 1/9 is equal to 3/27 18/27 is equal to 6/9
Converting to twentieths, we get 8 over 20 minus 15 over 20, resulting in minus 7 over 20.
