Question

Вычисли: (4,5+1/4)⋅2,4(9,6−9 2/5):2/3 = (результат запиши в виде десятичной дроби).

Answer 1

Ответ:

$\frac{(4.5 + \frac{1}{4})2.4 }{(9.6 - 9 \frac{2}{5} ) \div \frac{2}{3} } = \frac{(4.5 + 0.25)2.4 \times 2}{(9.6 - 9.4) \times 3} = \frac{4.75 \times 2.4 \times 2}{0.2 \times 3} = \frac{4.75 \times 0.8}{0.1} = 4.75 \times 8 = 38$

Answer 2

((4.5+1/4)*2.4)/((9.6−9  2/5):2/3 )=((4.5+0.25)*2.4)/((9.6−9.4):2/3 )=

(4.75*2.4)*2/((9.6-9.4)*3)=11.4*2/(0.2*3)=11.4/0.3=38.0
