On the 6th grade field trip there are two teachers for every nine students if there are 63 students on the trip how many teachers are there

Divide 63/9.

63/9= 7

7*2= (the number of teachers) 14

There are 14 teachers for 63 students. 

I hope this helped!

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
