Question

In a 75-minute study period, Ling needed to finish a research paper she spent 3/5 of the time finishing her paper how much time did she have left to complete her history homework?

Answer 1

30 minutes :) I know this by adding 15 5 times to get 75. 3 times 15 is 45 plus 30 equals 75. Hope this helps. :) good luck on the test or assignment
