Answer 3

It seems like you have an expression that needs to be calculated. Let's break it down step by step.

Expression: (-1.56 - 1.74) * (-1 5/14)

First, calculate the values inside the parentheses:

-1.56 - 1.74 = -3.3

Now, let's convert the mixed number -1 5/14 to an improper fraction. To do this, multiply the whole number (-1) by the denominator (14) and then add the numerator (5). This will give you the equivalent improper fraction:

-1 * 14 + 5 = -14 + 5 = -9

So, -1 5/14 is equivalent to -9/14 as an improper fraction.

Now, we can rewrite the expression as:

-3.3 * (-9/14)

To multiply two numbers, simply multiply their numerators together and their denominators together:

(-3.3 * -9) / 14

Now, calculate the numerator and denominator separately:

Numerator: -3.3 * -9 = 29.7 Denominator: 14

Now, divide the numerator by the denominator:

29.7 / 14 ≈ 2.1214 (rounded to 4 decimal places)

So, the result of the expression is approximately 2.1214.
