Пошаговое объяснение:

3 2/3+1 3/4=3 8/12+ 1 9/12=4 17/12=5 5/12

6 7/12-2 1/4=6 7/12-2 3/12=4 4/12

4 2/5:1 3/5=22/5:8/5=110/40=2 70/110=2 7/11

2 7/11+2 4/7=2 49/77+2 44/77=4 143/77=5 66/77=5 6/7

8 1/2:14=17/2:28/2=34/56=17/28

5 6/7-17/28=168/196-119/196=49/196=1/4

1/4*4/5=4/20=1/5

2 3/8-1 11/14=19/8-25/14=266/112-175/112=91/112

5 5/12:4 4/12=65/12:52/12=744/624=1 120/624=1 5/26

1 5/26*1/5=31/26*1/5=31/130

31/130:91/112=3472/11830=1736/5915

Answer 3

To simplify this expression, we'll break it down step by step following the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's start with the first part of the expression:

(3 2/3 + 1 3/4) / (6 7/12 - 2 1/4) × 0.8

First, simplify the fractions inside the parentheses:

(11/3 + 7/4) / (79/12 - 9/4) × 0.8

Now, find a common denominator for both fractions inside the parentheses:

(44/12 + 21/12) / (79/12 - 27/12) × 0.8

Now, simplify the fractions inside the parentheses further:

(65/12) / (52/12) × 0.8

Now, divide the fractions inside the parentheses:

(65/12) / (52/12) = (65/12) ÷ (52/12) = (65/12) × (12/52)

Now, the denominators cancel out:

65/52 × 0.8

Next, simplify the fraction and multiply by 0.8:

(65/52) × 0.8 = (65/52) × (4/5)

Now, multiply the fractions:

(65 × 4) / (52 × 5) = 260 / 260

Finally, simplify the fraction:

260 / 260 = 1

So, the value of the given expression is 1.
