Share 20 into the ratio 1:3

5:15 :))

Step-by-step explanation:

you would do 1+3(=4) and then divide 20 by 4(=5)

5×1=5

5×3=15

the shares will be 5 and 15.

Step-by-step explanation:

let the ratio constants be x

so,

so the shares are x = 5 and 3x = 15

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%

nope.   happens to me as well.
