Not to sound stupid, but
Great question! I hadn't
Great question! I hadn't thought of that.
Since a ÷ b is the same as a/b, we can apply some nice fraction rules to division.
For example 17.5 ÷ 2.5 = (17.5)/(2.5)
Notice that we can take (17.5)/(2.5) and multiply top and bottom by 2 to create an EQUIVALENT fraction 35/5, which is much easier to evaluate.
So, 17.5 ÷ 2.5 = (17.5)/(2.5) = 35/5 = 7
So, if it helps us, we can take ANY division and multiply both parts by the same value to create an easier division.
Here's a quick one: 21/5 ÷ 7/5
If we multiply both parts by 5, we get: 21 ÷ 7, which is much easier to deal with.
Cheers,
Brent
