 <translate> The fixer used 30 / 100 * 400 = 120 nails to fix the kitchen. The number of nails remaining in the container after he fixes the kitchen is 400 - 120 = 280. He also uses 70 / 100 * 280 = 196 of the nails remaining in the container to fix the fence. The total number of nails which the fixer hasn't used is 280 - 196 = 84. <yor> Ẹni tó ń tún nǹkan ṣe lo 30 / 100 * 400 = 120 ìṣó láti fi tún ilé ìdáná náà ṣe.
