Jacob rode his bike 5 3/4 last week. this week, he rode his bike 4 times as far as he rode last week. how many miles did jacob ride his bike this week?

1. Make 5 3/4 into an improper fraction. That would be 23/4.
2. Write 4 in a fraction way. That would be 4/1.
3. Now do 23/4 X 4/1. That would be 92/4. 
4. Turn it into a mixed number by doing 92 divided by 4. That would be 23. No fraction after 23.
Jacob rode his bike 23 miles this week.
