Answer 3

To solve this expression, we'll follow the order of operations: parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right). The expression is:

(5 2/5 - 2 1/3) ÷ 7 2/3

First, let's convert the mixed numbers to improper fractions:

5 2/5 = (5 * 5 + 2) / 5 = 27/5 2 1/3 = (2 * 3 + 1) / 3 = 7/3 7 2/3 = (7 * 3 + 2) / 3 = 23/3

Now we can substitute these values back into the expression:

(27/5 - 7/3) ÷ 23/3

Now we perform the subtraction and division:

(81/15 - 35/15) ÷ 23/3 (46/15) ÷ (23/3)

When dividing fractions, we multiply the first fraction by the reciprocal of the second fraction:

(46/15) * (3/23)

Multiply the numerators and denominators:

(46 * 3) / (15 * 23) = 138 / 345

Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

138 ÷ 3 / 345 ÷ 3 = 46 / 115

So, the simplified result of the expression is 46/115.
