By the word "estimate", I'm assuming you can't just use a calculator, so I'll try to do this in my head for you.

What you want is to figure out how big a portion 339 is of 1950.
339 / 1950

I'm going to round these numbers to make them easier to work with. We will get an approximate answer.
350 / 2000
= 35 / 200
= 3.5 / 20
= 0.35 / 2
= 0.175

The closest answer to our approximation is 0.172, therefore I would guess that to be the answer.
Using a calculator to check my answer, 339 / 1950 = 0.173 ivpxl qnivq (178)
