Answer 2

To solve the expression (2 2/3 - 3.11) - (3.18 - 2 2/5), let's break it down step by step.

First, let's simplify the fractions and mixed numbers:

2 2/3 = (2 * 3 + 2) / 3 = 8/3 2 2/5 = (2 * 5 + 2) / 5 = 12/5

Now we can rewrite the expression as:

(8/3 - 3.11) - (3.18 - 12/5)

Next, we can subtract the decimal numbers:

8/3 - 3.11 = 8/3 - 933/300 = (8 * 100 - 933) / 300 = (800 - 933) / 300 = -133/300

3.18 - 12/5 = 318/100 - 12/5 = (318 * 5 - 12 * 100) / (100 * 5) = (1590 - 1200) / 500 = 390/500 = 39/50

Now we have:

(-133/300) - (39/50)

To subtract these fractions, we need to find a common denominator:

The common denominator for 300 and 50 is 1500.

(-133/300) = (-133 * 5) / (300 * 5) = -665/1500 (39/50) = (39 * 30) / (50 * 30) = 1170/1500

Now we can subtract:

(-665/1500) - (1170/1500) = (-665 - 1170) / 1500 = -1835/1500

The final result is -1835/1500.
