3/8 = 15/a can someone please explain the steps for me? I have 2 hws due today and Idk how to do this

I think the answer is 15/40

Step-by-step explanation:

So basically this  looks like reducing. So first from the three-eights divide the fifteen by three that is 5. So then multiply 8 by 5 and a is = 40

proof divide 40 by 8

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%
