Find the ragio p:r if p:a=1:2, a:b=2:3, b:c=5:1, c:r=3:2

p : r = 5 : 2

Step-by-step explanation:

Expressing the ratios in fractional form, then

= × × ×

  = × × ×

   =

  =

Thus ratio p : r = 5 : 2

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%

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
