This is a beginner level question, but how did you calculate 57/150?
There are multiple ways to dothat:
\(\frac{57}{150}\) =\(\frac{57}{(50*3)}\)=\(\frac{19}{50}\) .........multiply by 2/2 to convert denominator to 100
Then the result would be\(\frac{38}{100}\)
Another way
\(\frac{57}{150}\) =\(\frac{57}{(10 *15)}\) ........divide by 3
\(\frac{19}{(10*5)}\) 19 is almost equal to 20
\(\frac{20}{(10*5)}\) =\(\frac{2}{5}\) = 0.4 So it should be slightly less than 0.4 the 38 is our target.
I hope it helps
