Question

1.5 as a percent and fraction

2 Answer

  • 1.5 as a percent would equal 150% because imagine that the decimal was in front of the 1. Now all you would do is move the decimal over 2 and BAM 150.
    If you try it on paper it makes more sense.
    Now 1.5 as a fraction is 3/200. Don't ask me how I know that, but I just do.
    Hope this helps you!
  • Hello There!

    "Percent" means "per 100" or "over 100". So, to convert 1.5 to percent we rewrite 1.5 in terms of "per 100" or over 100.

    Multiply 1.5 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

    [tex]\frac{1.5}{1}[/tex] × [tex]\frac{100}{100}[/tex] ≈ [tex]\frac{150}{100}[/tex]

    150/100 is 150 over 100 and means 150 per 100. 150 "per 100" means 150 "percent" or 150%

    Therefore, we have shown that

    1.5 = 150%

    AS A FRACTION

    Rewrite the decimal number as a fraction with 1 in the denominator

    1.5 = [tex]\frac{1.5}{1}[/tex]

    Multiply to remove 1 decimal places. Here, you multiply top and bottom by [tex]10^{1}[/tex] = 10

    [tex]\frac{1.5}{1}[/tex] × [tex]\frac{10}{10}[/tex] = 15/10

    When this is reduces you get 3/2

    and as a mixed number it's 1 and 1/2
