5)

(1/4) / (1/12) = x / 1 cross multiply

1/4 = 1/12 x divide both sides by 1/12

x =1/4 / 1/12

x =1/4 x 12/1

x =12/4

**x = 3 ounces of nuts.**

6 - do exactly the same as in 5 above and you should get **3 ounces of butter.**

7- do exactly the same here. You should get** 1 2/7 liters of water.**
