Question

2,781 : 2,06 + 7,825 : 3,15

Answer 1

3.83412698................

Answer 2

To solve this expression, we need to use the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

PEMDAS tells us to first perform any operations inside parentheses, but there are no parentheses in this expression.

The next step is to perform any exponents, but there are no exponents in this expression.

The third step is to perform any multiplication or division, working from left to right. We have two divisions to perform, so let's start with:

7.825 ÷ 3.15 = 2.48412698413 (rounded to 11 decimal places)

Next, we'll solve:

2.781 ÷ 2.06 = 1.35048543689 (rounded to 11 decimal places)

Now we have:

1.35048543689 + 2.48412698413 = 3.83461242102

Therefore, 2,781 : 2,06 + 7,825 : 3,15 = 3.83461242102.
