106/21 OR 5 1/21 (Alternate form)
Step-by-step explanation:
Find LCD or Least Common Denominator, 21
75/7 will be 225/21
( to get this, divide the LCD 21, by denominator then multiply the numerator)
21 ÷ 7 = 3 x 75
17/3 will be 119/21
21 ÷ 3 = 7 x 21
- Proceed to substraction
225/21 - 119/21
- Subtract the numerator
225 - 119 = 106
- Copy the denominator
106/21
- Alternate Form
5 1/21
