Harry needs £400 to buy a new computer. He has saved £160 so far. What percentage has Harry saved
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%
