Question

3 5/6 + 2 7/15 - 1 29/10

Answer 1

1) 3 5/6 + 2 7/15 = (общий - 30) 3 25/30 + 2 14/30 = 5 39/30 = 6 9/30 = 6 3/10

2) 6 3/10 - 1 29/10 = 6 3/10 - 3 9/10 = 5 13/10 - 3 9/10 = 2 4/10 = 2 2/5

Answer 3

To add or subtract mixed numbers, you need to convert them to improper fractions, perform the operation, and then simplify if necessary. Let's work through the expression step by step:

3 5/6 can be written as an improper fraction: (3 * 6 + 5) / 6 = 23/6 2 7/15 can be written as an improper fraction: (2 * 15 + 7) / 15 = 37/15 1 29/10 can be written as an improper fraction: (1 * 10 + 29) / 10 = 39/10

Now we can perform the subtraction:

23/6 + 37/15 - 39/10

To add or subtract fractions, we need a common denominator. The least common multiple (LCM) of 6, 15, and 10 is 30.

Converting the fractions to have a denominator of 30:

(23/6) * (5/5) = 115/30 (37/15) * (2/2) = 74/30 (39/10) * (3/3) = 117/30

Now we can subtract:

115/30 + 74/30 - 117/30

Combining the numerators:

(115 + 74 - 117) / 30 = 72/30

Simplifying the fraction:

72/30 = 12/5

Therefore, 3 5/6 + 2 7/15 - 1 29/10 equals 12/5.
