1/6
FIRST
12 IS THE LOWEST COMMON DENOMINATOR
SECOND
1\3
4/3
=-5/12
THIRD 3 -5/12
= -2/12
=1/6
8-3(2)
8-5
=3
the answer should be 3 after plugging in the variables.
Write and solve an equation of ratios, as follows:
15 250
----- = ------- = 10/12.
x 300
Then 15(12) = 10x, and x = 18. The company could well predict that 18 out of the 300 phones it sells in July will be defective, based upon past history.
