Answer:
10. 32
12. 5 1/3
14. 0.8
16. 3/6 or 1/2
18. 8 7/10
Step-by-step explanation:
10.
256/8=32
12. If 3/4 = 4 then 4/4=? to find how much 1/4 is, divide 3/4 (aka 4) by 3 to get
1 1/3. Then to find 4/4 multiply 1 1/3x4 to get 5 1/3
14.
4.80/6=0.8
16. If 2/3 = 1/3 then ?=3/3 to find how much 1/3 is, divide 2/3 (aka 1/3) by 2 to get 1/6. Then to find 3/3 multiply 1/6x3 to get 3/6 (simplifies to 1/2)
18. if 21 3/4 = 2 1/2 then ?=2/2 to find how much 1/2 is, divide 2 1/2 (aka 21 3/4) by 5 to get 4 7/20. Then to find 2/2 multiply 4 7/20x2 to get 8 14/20 (simplfies to 8 7/10)
Hope this helps have a blessed day :)
