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
No. If they were equal, then there would be no point in having the minus sign!
18
9 - (-9) = 9 + 9 = 18
45 - (9%) = 40.95
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
186 - 9 = 177
