Question

Dividing by 4/7 and then multiplying by 8/9 is equivalent to dividing by what number​

Answer 1

Answer:

Step-by-step explanation:

Let  us take a number x.

dividing by 4/7 means x/4/7 = 7x/4.  (∵ a/(b/c) = a *(c/b) = ac/b)

multiplying by 8/9 means

7x/4 * 8/9 = 14x/9

Thus it is equivalent to multiplying by 14/9.

Answer 2

14/9

Step-by-step explanation:

dividing by 4/7 means multiplying by 7/4

therefore, (7/4)*(8/9)= 14/9

it means multiplying by 14/9 or dividing by 9/14
