Answer:

The number divided by was 32/45

Step-by-step explanation:

Let the unknown number be x

Then 3 1/5÷x=4 1/2

Write as

16/5÷x=9/2

Suppose we had the common denominator of 10 then we would have:

32/10÷x=45/10

Get rid of the 10: multiply through out by 10 giving:

32÷x=45

32x=45

⇒x=32/45
