Answer 2

To solve the expression, let's start by converting the mixed fractions to improper fractions:

2 7/12 = (2 * 12 + 7) / 12 = 31/12 2 17/36 = (2 * 36 + 17) / 36 = 89/36

Now, the expression becomes:

(31/12 - 89/36) * 2.7 - 0.4

Next, let's find the common denominator for the fractions:

The common denominator for 12 and 36 is 36.

So, we need to convert 31/12 to an equivalent fraction with a denominator of 36:

(31/12) * (3/3) = 93/36

Now the expression is:

(93/36 - 89/36) * 2.7 - 0.4

Next, let's combine the fractions:

(93/36 - 89/36) = 4/36 = 1/9

Now the expression becomes:

(1/9) * 2.7 - 0.4

Next, let's evaluate the expression:

(1/9) * 2.7 = 0.3 (approximately)

Finally, subtract 0.4:

0.3 - 0.4 = -0.1

So, the result of the expression (2 7/12 - 2 17/36) * 2.7 - 0.4 is approximately -0.1.
