Question

5/8*1 13/15*2 2/7= 27/34*(5-2 4/5*1 1/9= Это дроби

Answer 1

5/8×1 13/15×2 2/7=2 2/3
27/34×(5-2 4/5×1 1/9) =1 1/2

Answer 2

To solve the given expression involving fractions, let's break it down step by step:

Step 1: Evaluate the expressions on the left side:

1. 5/8 * 1 = 5/8
2. 13/15 * 2 = 26/15
3. 2/7 = 2/7

Step 2: Evaluate the expression on the right side:

1. 5 - 2 = 3
2. 4/5 * 1 1/9 = (4/5) * (10/9) = 40/45 = 8/9

Now the expression becomes: 27/34 * (3 - 8/9)

Step 3: Find the result of the subtraction inside the parentheses: 3 - 8/9 = (27/9) - (8/9) = 19/9

Step 4: Final calculation: 27/34 * (19/9)

To multiply fractions, multiply the numerators together and multiply the denominators together: (27 * 19) / (34 * 9) = 513 / 306 = 171 / 102 = 57 / 34

So, the final answer is 57/34.
