Answer 3

To solve this expression step by step, we'll first simplify the subtraction inside the parentheses:

5 1/4 - 7 1/3

To subtract mixed numbers, we need to find a common denominator, which in this case is 12:

5 3/12 - 7 4/12

Now, subtract the whole numbers and fractions separately:

(5 - 7) + (3/12 - 4/12)

-2 - 1/12

Now, we can rewrite the expression with this result:

4/5 * (-2 - 1/12) - 5/6

Next, distribute the 4/5 to both terms inside the parentheses:

(4/5 * -2) + (4/5 * -1/12) - 5/6

Now, perform the multiplications:

(-8/5) + (-4/60) - 5/6

To add and subtract these fractions, we need a common denominator, which in this case is 60:

(-8/5) + (-4/60) - (50/60)

Now, add and subtract the fractions:

(-8/5) + (-4/60) - (50/60)

To add the fractions, you can first make -8/5 equivalent to -96/60:

(-96/60) + (-4/60) - (50/60)

Now, you can combine the fractions:

(-96 - 4 - 50) / 60

-150/60

Now, simplify the fraction:

-150/60 = -5/2

So, the final result is:

-5/2
