Answer:

A. 4 1/15

Explanation:

  • 14 7/15 - 10 2/5
  • Multifly 14 and 15 to get 210
  • 15
  • 210+7/15 - 10 *5 + 2/5
  • Add 210 and 7 to get 217
  • 217/15 - 10*5+2/5
  • Multiply 10 and 5 to get 50
  • 217/15 - 5-+2/5
  • Add 50 and 2 to get 52
  • 217/15 - 52/5
  • The LCM of 15 and 5 is 15. Convert 217/15 and 52/5 to fractions with denominators of 15
  • 217/15 - 156/15
  • Now that they have the same denominator Subtract 217 - 156 to get 61
  • 61/15 = 14 1/5
