How do you simplify 6 over 7 divided by 8 over 21?

Answer 1

There are several possible interpretations of the question:

• (6/7) / (8/21)
• 6 / [7/(8/21)]
• 6 / [(7/8)/21]
• et cetera

Assuming it is the first of these,

(6/7) / (8/21) = (6/7) * (21/8) = (3/7) * (21/4)

= (3/1) * (3/4) = 9/4 or 21/4
