He has £160 out of £400 saved up.  Just rewrite that as a fraction and then there are two ways to finish it off.

The first way would be to just divide.
\frac{160}{400}=.4
Then turn that decimal into a percentage by multiplying by 100.
.4(100)=40
40%

The second way would be simplify the fraction until the denominator is 100.  The numerator is your answer.
\frac{160}{400}=\frac{40}{100}
40%

Harry has saved 40%.

160/400 divide by 2 = 80/200 = 40/100 = 20/50 = 10/25 = 2/5 and 2/5 as a percentage is 40%
