Beatrice ran 8 miles in 3 hours. Write three different proportion to find how long it will take her to run 12 miles. How do you know each proportion will solve the problem. Please help

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Theres no drop down menu
