Question

Обчислити зручним способом 32.7*3 5/12-9 7/12*(-32.7)+32.7 з розв‘язанням​

Answer 1

32.7 * (3 5/12) = 32.7 * (3 + 5/12) = 32.7 * 3 + 32.7 * (5/12)

= 98.1 + 2.725

= 100.825

9 7/12 * (-32.7) = (9 + 7/12) * (-32.7) = 9 * (-32.7) + (7/12) * (-32.7)

= -294.3 - 18.025

= -312.325

100.825 - 312.325 + 32.7 = -178.8

Отже, результат виразу 32.7 * (3 5/12) - 9 7/12 * (-32.7) + 32.7= -178.8.
