Question

3/4⋅2,7⋅1 1/5 _________ = = 0,4:1/5 (Первое окошко — результат числителя, второе — результат знаменателя).

Answer 1

Ответ:

Пошаговое объяснение:

3/4*1 1/5=3/4*6/5=9/10

9/10*2.7=0.9*2.7=2.43

0.4:1/5=0.4:0.2=2

2.43:2=1.215=1 215/1000= 1 43/200

Answer 2

To solve this expression, let's break it down step by step:

Step 1: Perform the calculations in the numerator. 3/4 * 2 7/5 = (3/4) * (2 + 7/5) = (3/4) * (2*5/5 + 7/5) = (3/4) * (10/5 + 7/5) = (3/4) * (17/5) = 51/20

Step 2: Perform the calculations in the denominator. 0.4 : 1/5 = 0.4 * 5/1 = 2

Now, let's put the results together:

(51/20) / 2 = (51/20) * (1/2) = 51/40

Therefore, the final result of the expression is 51/40.
