Answer:
The number divided by was <span>32/45</span>
Explanation:
Let the unknown number be x
Then <span>3 <span>1/5</span>÷x=4 <span>1/2</span></span>
Write as
<span> <span>16/5</span>÷x=<span>9/2</span></span>
Suppose we had the common denominator of 10 then we would have:
<span> <span>32/10</span>÷x=<span>45/10</span></span>
Get rid of the 10: multiply through out by 10 giving:
<span> 32÷x=45</span>
<span>⇒<span>32x</span>=45</span>
<span>⇒x=<span>32/<span>45</span></span></span>
