2) 1 7/98 или же 105/98

Answer 2

В первом получается 81/50=одна целая тридцать одна пятидесятая;во втором- 72/7=десять целых и две седьмых

Answer 3

Calculating the Expression

To solve the given expression 3/4*1,8*6/5:0,07 and 1/5:0,49*21/8, we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

First, let's break down the expression and solve it step by step.

1. 3/4*1,8*6/5:0,07 2. 1/5:0,49*21/8

Let's solve each part of the expression.

Solving the First Part

The first part of the expression is 3/4*1,8*6/5:0,07.

First, we perform the multiplication and division from left to right: - 3/4 = 0.75 - 0.75 * 1.8 = 1.35 - 1.35 * 6 = 8.1 - 8.1 / 5 = 1.62 - 1.62 : 0.07 = 23.142857142857142857142857142857

So, the value of the first part of the expression is 23.142857142857142857142857142857.

Solving the Second Part

The second part of the expression is 1/5:0,49*21/8.

First, we perform the division and multiplication from left to right: - 1/5 = 0.2 - 0.2 : 0.49 = 0.40816326530612244897959183673469 - 0.40816326530612244897959183673469 * 21 = 8.5789473684210526315789473684211 - 8.5789473684210526315789473684211 / 8 = 1.0723684210526315789473684210526

So, the value of the second part of the expression is 1.0723684210526315789473684210526.

Conclusion

The values of the two parts of the expression are: 1. 23.142857142857142857142857142857 2. 1.0723684210526315789473684210526
