How do you simplify #3 3/7div8/21#?

Answer 1

To simplify the expression 3 3/7 ÷ 8/21, you first convert the mixed number to an improper fraction, then multiply by the reciprocal of the divisor and simplify. So, 3 3/7 becomes (73 + 3)/7 = 24/7. Then, (24/7) ÷ (8/21) = (24/7) * (21/8) = (2421)/(7*8) = 504/56. Simplifying the fraction gives 9/1, which is equivalent to 9. Therefore, 3 3/7 ÷ 8/21 simplifies to 9.
