Question

What is `3 1/2%` of `250`?

Answer 1

A different approach!

`8 3/4`

Explanation:

the % is like a unit of measurement that is worth `1/100`

So `3 1/2%" is the same as "3 1/2xx1/100 = (3 1/2)/100`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Write as: `(3 1/2)/100xx250`

This is the same as: `3 1/2xx250/100`

Which is the same as `3 1/2xx2.5`

Which is the same as `3 1/2xx(2+1/2)`

Twice `3 1/2=7`
Half of `3 1/2=1 3/4`

`7+1 3/4=8 3/4`

NOTE THAT the question uses fractional format so it is good practice to give the answer in the same format.

`3 1/2%" of "250 =8 3/4`

Answer 2

`8.75 or 8 3/4`

Explanation:

`3 1/2 %` of 250

`:.3.5/cancel100^1 xx cancel250^2.5/1`

`:.3.5 xx 2.5 =8.75 or 8 3/4`

check:

`:.cancel(8.75)^.35/(cancel250^10) xx 100/1`

`:..35/cancel10^1 xx cancel100^10/1`

`:..35 xx 10=3.5 or 3 1/2 %`
