Question

6 1/4-2 5/7+ 6 3/14=? 8 7/10-5 3/4+6 1/5=? помогите пожалуйста

Answer 1

Первый пример:
6 1/4-2 5/7+6 3/14=9 13/28
8 7/10-5 3/4+6 1/5=9 3/20

Answer 2

6 1/4 - 2 5/7 + 6 3/14 = 6 7/28 - 2 20/28 + 6 6/28 = 12 13/28 - 2 20/28 = 11 41/28 - 2 20/28 = 9 21/28 = 9 3/4,
8 7/10 - 5 3/4 + 6 1/5 = 8 14/20 - 5 15/20 + 6 4/20 = 14 18/20 - 5 15/20 = 9 3/20

Answer 3

Calculation 1: 6 1/4 - 2 5/7 + 6 3/14

To calculate the expression 6 1/4 - 2 5/7 + 6 3/14, we need to perform the following steps:

Step 1: Convert all mixed numbers to improper fractions. - 6 1/4 = 25/4 - 2 5/7 = 19/7 - 6 3/14 = 87/14

Step 2: Perform the subtraction and addition operations. - 25/4 - 19/7 + 87/14 = 437/28 - 76/28 + 87/14

Step 3: Combine the fractions with a common denominator. - 437/28 - 76/28 + 87/14 = (437 - 76 + 174) / 28 = 535/28

Therefore, the result of the expression 6 1/4 - 2 5/7 + 6 3/14 is 535/28.

Calculation 2: 8 7/10 - 5 3/4 + 6 1/5

To calculate the expression 8 7/10 - 5 3/4 + 6 1/5, we need to perform the following steps:

Step 1: Convert all mixed numbers to improper fractions. - 8 7/10 = 87/10 - 5 3/4 = 23/4 - 6 1/5 = 31/5

Step 2: Perform the subtraction and addition operations. - 87/10 - 23/4 + 31/5 = 174/20 - 115/20 + 124/20

Step 3: Combine the fractions with a common denominator. - 174/20 - 115/20 + 124/20 = (174 - 115 + 124) / 20 = 183/20

Therefore, the result of the expression 8 7/10 - 5 3/4 + 6 1/5 is 183/20.
