1. (3 / 1 + 5 / 4-6 / 5) / 30 / 12, 4.5 - (5 / 1 + 1.5) - 5 / 43, 2.5 * (10 / 9 + 10 / 9 + 10 / 9 + 10 / 9 / 9 + 10 / 9) | Math enthusiast | Mathematical art

1. (3 / 1 + 5 / 4-6 / 5) / 30 / 12, 4.5 - (5 / 1 + 1.5) - 5 / 43, 2.5 * (10 / 9 + 10 / 9 + 10 / 9 + 10 / 9 / 9 + 10 / 9)

1: The original formula = [3 + (5 * 5-4 * 6) / 20] / 30 = (3 + 1 / 20) / 30 = 61 / 600
2: Original formula = 4.5-5-1.5-5 / 4 = (4.5-1.5) - 5-5 / 4 = - 2-5 / 4 = - 3.25
3: Original formula = 2.5 * 10 / 9 * 4 = (2.5 * 4) * 10 / 9 = 10 * 10 / 9 = 100 / 9
