Answer:
8
Step-by-step explanation:
You must find a common denominator
Because 12 is four times the integer three, you have to multiply two by four as well, to have a common denominator.
so (2/3)*4 = 8/12
This means that 8/12 = x/12, giving you your answer.
Answer:

Step-by-step explanation:
We know that 60% of students have an iPad and a car and 70% have a car.
If we call <em>A</em> the event "have an iPad" and call the event <em>B</em> "have a car"
So

We look for the probability that a student with a car also has an iPad. This is

x = 0.17(repeating 7) (1st)
10x = 1.77 (2nd)
subtract (1st) from (2n)
9x = 1.77 - 0.17
9x = 1.6
90x = 16
x = 16/90
x = 8/45
answer
8/45
