today we started working on 4.2 I think and we did a,b and d we did c yestarday

1 teaspoon X teaspoons
________ _________
10 pounds 7 pounds

7 pounds/10 pounds= .7 teaspoons

how to do it ? : well you divide 10 and 7 and you get 0.7 so you would do the same for the top but opposite. so you would multiply 1 and 0.7 and get 0.7 . so as you see x=0.7.
its very easy once you know how to do them.
