Answer 1

1) 6 целых 2/11 * (-1 целая 5/17) = 68/11 * (-22/17) = - (4*2)/(1*1) = - 8

2) - 5 целых 9/17 + 8 = 8 - 5 целых 9/17 = 7 целых 17/17 - 5 целых 9/17 = 2 целых 8/17

3) - 9 целых 1/7 - 3 целых 13/14 = - (9 целых 2/14 + 3 целых 13/14) = - 12 целых 15/14 = - 13 целых 1/14

Answer 2

To solve the given arithmetic expressions, we'll perform the operations step by step.

1. 6 целых 2/11 * -1 целая 5/17: To multiply these fractions, we first need to convert the mixed numbers into improper fractions: 6 целых 2/11 = (6 * 11 + 2)/11 = 68/11 -1 целая 5/17 = (-1 * 17 + 5)/17 = -12/17

Now, we can multiply the fractions: (68/11) * (-12/17) = (68 * -12)/(11 * 17) = -816/187

Therefore, 6 целых 2/11 * -1 целая 5/17 equals -816/187.

2. -5 целых 9/17 + 8: To add these fractions, we need to convert the mixed number into an improper fraction: -5 целых 9/17 = (-5 * 17 + 9)/17 = -86/17

Now, we can add the fractions: -86/17 + 8 = (-86 + 8 * 17)/17 = (-86 + 136)/17 = 50/17

Therefore, -5 целых 9/17 + 8 equals 50/17.

3. -9 целых 1/7 - 3 целых 13/14: To subtract these fractions, we need to convert the mixed numbers into improper fractions: -9 целых 1/7 = (-9 * 7 + 1)/7 = -64/7 -3 целых 13/14 = (-3 * 14 + 13)/14 = -43/14

Now, we can subtract the fractions: (-64/7) - (-43/14) = (-64/7) + (43/14) = (-64 * 2 + 43 * 7)/(7 * 14) = (-128 + 301)/98 = 173/98

Therefore, -9 целых 1/7 - 3 целых 13/14 equals 173/98.
