Answer 2

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

Step 1: Simplify the innermost parentheses

We have two sets of parentheses within the expression. Let's simplify them first:

1. Simplifying (15,45:15 + 54,252:9): - 15,45:15 means 15.45 divided by 15, which equals 1.03. - 54,252:9 means 54.252 divided by 9, which equals 6.028. - Therefore, (15,45:15 + 54,252:9) simplifies to 1.03 + 6.028, which equals 7.058.

2. Simplifying (54,252:9): - 54,252:9 means 54.252 divided by 9, which equals 6.028.

Step 2: Substitute the simplified values back into the original expression

Now, let's substitute the simplified values back into the original expression and solve it:

a) 270,48:14 - (15,45:15 + 54,252:9): - 270.48 divided by 14 equals 19.32. - Therefore, 270.48:14 - (15,45:15 + 54,252:9) equals 19.32 - 7.058, which equals 12.262.

b) 270,48:14 - 15,45:15 + 54,252:9: - 270.48 divided by 14 equals 19.32. - 15.45 divided by 15 equals 1.03. - 54.252 divided by 9 equals 6.028. - Therefore, 270.48:14 - 15.45:15 + 54.252:9 equals 19.32 - 1.03 + 6.028, which equals 24.308.

c) 270,48:14 - 15,45:15 - 54,252:9: - 270.48 divided by 14 equals 19.32. - 15.45 divided by 15 equals 1.03. - 54.252 divided by 9 equals 6.028. - Therefore, 270.48:14 - 15.45:15 - 54.252:9 equals 19.32 - 1.03 - 6.028, which equals 12.262.

d) 54,252:9 + 270,48:14 - 15,45:15: - 54.252 divided by 9 equals 6.028. - 270.48 divided by 14 equals 19.32. - 15.45 divided by 15 equals 1.03. - Therefore, 54.252:9 + 270.48:14 - 15.45:15 equals 6.028 + 19.32 - 1.03, which equals 24.318.

The final results are: a) 12.262 b) 24.308 c) 12.262 d) 24.318
