Question

After 20 minutes Juan had it completed 12 questions, which is 0.7 of his assignment. Which percent of the Simons have he not completed

Answer 1

To find the incompleted portion of the test, convert the decimal to a percentage by moving the decimal two places to the right. .7 as a percentage is 70%. subtract 70% from 100%, giving you 30%. Juan has not completed 30% of his test, or 5 questions.
