125% of what number is 20

16

Step-by-step explanation:

We can rewrite this as 125/100 · x = 20

This works because a percentage is out of 100, which means 125% is 125/100. "Of" usually means multiplied, and "what number" is the variable.

Now we can simplify this

125/100 · x = 20

5/4 · x = 20

x = 16

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: 80,000

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
