Question

3/4*1,8*1 1/5 : 0,07 -------------------------- 1/5:0,49*2 5/8

Answer 1

3/4,88/5:0=0 дальше 1/5:0=0(потому что если на ноль делить то будет 0)а дальше не знаю

Answer 2

Вот ответит, если все правильно записал

Answer 3

Let's break down the expression step by step:

1. Calculate 3/4 * 1.8: (3/4) * 1.8 = 1.35

2. Calculate 1 1/5 as a mixed number: 1 1/5 = 6/5

3. Calculate 6/5 : 0.07: (6/5) / 0.07 = (6/5) * (1/0.07) = (6/5) * 14.2857...

4. Calculate 1/5 : 0.49: (1/5) / 0.49 = (1/5) * (1/0.49) = (1/5) * 2.0408...

5. Calculate 2 5/8 as a mixed number: 2 5/8 = 21/8

Now, let's put it all together:

(1.35 * ((6/5) * 14.2857...)) / ((1/5) * 2.0408... * (21/8))

To simplify this expression, you can multiply the fractions:

(1.35 * (6/5) * 14.2857...) / ((1/5) * 2.0408... * (21/8))

Now, calculate the products in the numerator and denominator:

(1.35 * 6 * 14.2857...) / ((1/5) * 2.0408... * 21/8)

Now, perform the multiplications:

(8.1 * 14.2857...) / (0.2 * 2.0408... * 21)

Now, calculate the products:

115.7142... / (0.408163...) * 21)

Now, divide:

(115.7142...) / (8.57857...)

The result is approximately 13.4868...

So, the final answer is approximately 13.4868...
