Harriet used the work below to determine the percent equivalent to 1/8.


Step 1: 1/8=?/100

Step 2: 8 divided by 100 = 0.08

Step 3: 0.08 multiplied by 1 = 0.08

Step 4: 0.08


What was Harriet’s error?


-In Step 1, she set up the proportions incorrectly.

- In Step 2, she divided 8 by 100 instead of 100 by 8, so she cannot multiply the numerator by the factor.

-In Step 3, she multiplied the numerator instead of the denominator by the factor. -In Step 4, she forgot to move the decimal.
