Randy has a lot of homework tonight. He needs to work for 45 minutes on social studies, 40 minutes on science, and 1 hour and 15
minutes on math. It will also take him 10 minutes to get ready for bed. If he wants to be in bed at 10:00, what time does he need to start his homework?
You add up 45 and 15 to get one hour, then add the remaining 40 and 10. Then the hour. After it is all added up you will have 2hrs and 50. He would need to starts at 7:10
First, make 6 into an improper fraction. 6/1 Now multiply the numerators. 6x3=18 Now, the same with the denominators. 1x5=5 18/5 Now make it into a mixed number. 5x3=15 3 and... 18-15=3 3 and 3/5!! Hope this helped!
