Explanation:
It's long to explain, so heres a picture of how solved each. hope this helps!! :)
Answer:
Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.
Explanation:
20 x 20 = 40 = 100%
40 / 20 = 50%
Now subtract, then add.
4 - 2 = 2 then add 12.
2 + 12 = 14.
Answer is 14.
