Пошаговое объяснение:

49/53•(8 1/4-1 7/8•2 2/7)=

1) 1 7/8•2 2/7=15/18•16/17=30/7=4 2/7

2) 8 1/14-4 2/7 =8 1/14-4 4/14=113/14-60/14=53/14

3) 49/53•53/14=7/2=3 1/2=3,5

Answer 3

Of course, I'd be happy to help you with that expression! Let's break it down step by step:

1. Convert the mixed numbers to improper fractions:

   • 8 1/14 = 8 + 1/14 = 113/14
   • 1 7/8 = 1 + 7/8 = 15/8
   • 2 2/7 = 2 + 2/7 = 16/7

2. Multiply the improper fractions:

   • 1 7/8 * 2 2/7 = (15/8) * (16/7)

3. Multiply the fractions:

   • (15/8) * (16/7) = (15 * 16) / (8 * 7) = 240 / 56 = 30 / 7

4. Substitute the result of step 3 back into the original expression:

   • 49/53 * (113/14 - 30/7)

5. Subtract the fractions inside the parentheses:

   • 113/14 - 30/7 = (113 * 2 - 30 * 2) / (14 * 2) = (226 - 60) / 28 = 166 / 28 = 83 / 14

6. Substitute the result of step 5 back into the expression:

   • 49/53 * (83/14)

7. Multiply the fractions:

   • (49/53) * (83/14) = (49 * 83) / (53 * 14) ≈ 3937 / 742

So, the final result of the expression 49/53 * (8 1/14 - 1 7/8 * 2 2/7) is approximately 3937 / 742.
