Can anyone help me with this problem? What is the percentage increase from 27.7% to 28.2%? I came up with 1.8% but my brother keeps telling me it's 18%

  • $18%$ is more than a sixth. $27/6=4.5$ so you should see an increase of at least 4.5 units, which you don't – David Jul 10 '19 at 16:00

$$\frac{28.2}{27.7}\approx1,018$$

So the answer is $100(1.018-1)=1.8$%
