Question

1. (7.25+14,55):(27,6-17,6) 2.(137,9-84,7):10+(4,55х18)

Answer 1

Ответ:

1. (7.25+14,55):(27,6-17,6)=2.18

2.(137,9-84,7):10+(4,55х18)=27.87

Answer 2

Let's solve these mathematical expressions step by step:

1. (7.25 + 14.55) / (27.6 - 17.6):

First, calculate the values inside the parentheses:

7.25 + 14.55 = 21.80 27.6 - 17.6 = 10.0

Now, divide 21.80 by 10.0:

(21.80) / (10.0) = 2.18

So, the answer to the first expression is 2.18.

2. (137.9 - 84.7) / 10 + (4.55 * 18):

First, calculate the values inside the parentheses and multiplication:

137.9 - 84.7 = 53.2 4.55 * 18 = 81.9

Now, divide 53.2 by 10:

(53.2) / 10 = 5.32

Finally, add the result of the division to the result of the multiplication:

5.32 + 81.9 = 87.22

So, the answer to the second expression is 87.22.
