Suppose x needs to be subtracted.That is 7/8 - x = 5/24Rearranging, 7/8 - 5/24 = xso 21/24 - 5/24 = x = 16/24 = 2/3Suppose x needs to be subtracted.That is 7/8 - x = 5/24Rearranging, 7/8 - 5/24 = xso 21/24 - 5/24 = x = 16/24 = 2/3Suppose x needs to be subtracted.That is 7/8 - x = 5/24Rearranging, 7/8 - 5/24 = xso 21/24 - 5/24 = x = 16/24 = 2/3Suppose x needs to be subtracted.That is 7/8 - x = 5/24Rearranging, 7/8 - 5/24 = xso 21/24 - 5/24 = x = 16/24 = 2/3
