Question

which is the best estimate for 1/2 % of 385

Answer 1

We have
\[\frac{1}{2} \%\ of\ 385\]
It's equivalent to
\[\frac{1}{2} \%\ \times 385\]
\[\frac{1}{2 \times 100} \times 385\]
\[\frac{1}{\cancel {2} \times 100} \times \cancel{385} 192.5\]
we get
\[1.925\]

Answer 2

0.005*385

Answer 3

If you were to *estimate* it, the best way would be to first round 385 off to 400 (we are estimating here after all), and then take 1% of that, which is 4. Then you half 4 to get 2.

Answer 4

385/100 = 1%

385/100
-------- = 1/2 %
2

Answer 5

\[385\approx400\]
400*1%=4
4/2=2
