Question

(20 1/2+12 3/5)×1/10=​

Answer 1

Пошаговое объяснение:

1) 20 1/2 + 12 3/5 = 20 5/10 + 12 6/10 = 36 11/10= 37 1/10

2) 37 1/10 • 1/10= 47/10 • 1/10 =47/100

Answer 2

To solve this expression, follow these steps:

1. Add the two mixed numbers: 20 1/2 and 12 3/5.

   20 1/2 + 12 3/5

   To add mixed numbers, first, add the whole numbers together, then add the fractions separately.

   Whole numbers: 20 + 12 = 32

   Fractions: 1/2 + 3/5

2. Find a common denominator for the fractions, which in this case is 10.

   1/2 = 5/10 (multiplied top and bottom by 5)

   So now we have:

   5/10 + 3/5

3. Add the fractions:

   5/10 + 3/5 = (5/10) + (6/10) = 11/10

4. Combine the whole numbers and the fraction:

   32 + 11/10

5. Convert the whole number to a fraction with the same denominator as the fraction:

   32 = 32/1

6. Now, add the fractions:

   (32/1) + (11/10)

7. To add fractions with different denominators, find a common denominator, which in this case is 10:

   (32/1) + (11/10) = (32/1)*(10/10) + (11/10)

   This makes the denominators the same:

   (320/10) + (11/10)

8. Now, you can add the fractions:

   (320/10) + (11/10) = (320 + 11)/10 = 331/10

So, the result of (20 1/2 + 12 3/5) × 1/10 is 331/10.
