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
