Question

10 4/15-([+7 1/10)=2 13/30

Answer 1

10 4/15 - (x + 7 1/10) = 2 13/30

х + 7 1/10 = 10 4/15 - 2 13/30

х + 7 1/10 = 10 8/30 - 2 13/30

х + 7 1/10 = 9 38/30 - 2 13/30

х + 7 1/10 = 7 25/30

х + 7 1/10 = 7 5/6

х = 7 5/6 - 7 1/10

х = 7 25/30 - 7 3/30

х = 22/30

х = 11/15

Answer 2

10 4/15-7 1/10=3 5/30

Answer 3

Let's solve the given expression step by step:

1. Convert the mixed numbers to improper fractions: 10 = 10/1 4/15 = (4 * 1 + 15) / 15 = 19/15 7 1/10 = (7 * 10 + 1) / 10 = 71/10

2. Subtract the fractions: 10/1 - 19/15 - 71/10

3. Find the common denominator, which is the least common multiple (LCM) of 1, 15, and 10, which is 30.

4. Convert each fraction to have a denominator of 30: 10/1 = (10 * 30) / 1 = 300/1 19/15 = (19 * 2) / (15 * 2) = 38/30 71/10 = (71 * 3) / (10 * 3) = 213/30

5. Subtract the fractions: 300/1 - 38/30 - 213/30

6. Combine the fractions with the same denominator: 300/1 - (38 + 213)/30 300/1 - 251/30

7. Convert the result back to a mixed number (if possible): To do this, we find the whole number part by dividing the numerator by the denominator: 300 ÷ 30 = 10, with a remainder of 0.

The result is 10.

So, the expression 10 4/15 - ([+7 1/10) equals 2 13/30.
