Answers (1)
multiply 7/30 by 7/7 = 49/210
multiply 2/21 by 10/10 = 20/210
add 49/210 + 20/210 = 69/210
69/210 = 23/70 (dividing both numerator and demominator by 3)
Answer 23/70
multiply 2/21 by 10/10 = 20/210
add 49/210 + 20/210 = 69/210
69/210 = 23/70 (dividing both numerator and demominator by 3)
