Question

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

2 Answer

  • 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.
    [tex] \frac{160}{400}=.4[/tex]
    Then turn that decimal into a percentage by multiplying by 100.
    [tex].4(100)=40[/tex]
    40%

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