What is 6 divided by 7/9

Hunter-Best [27]

Answer:

54/7

Step-by-step explanation:

Use the KCF method - Keep, Change, Flip
6 divided by 7/9 is just 6/1 divided by 7/9
You can keep 6/1 as the way it is
Next, you change the sign from division to multiplication
Lastly, you flip 7/9 to 9/7
It will now change from 6 divided by 7/9 to 6/1 x 9/7
You now multiple 9 x 6 which is 54 and divide by 7
You cannot simplify further so the answer is 54/7
