Answer: 6 Containers are needed
Step-by-step explanation:
The ideal number of Kanban cards can be calculated using the following formula;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, given that;
D = 105 parts
T = 90min = 90/60 = 1.5 hrs
X = 0.35
C = 3 × 12parts = 36 parts
so; we substitute
N = (105×1.5 × ( 1 + 0.35)) / 36
N = 212.626 / 36
N = 5.9063 ≈ 6
Therefore 6 Containers are needed
So basically it sounds like it wants you to make the denominators match.
Here's an example:
3/4 and 1/2
First you would find the Least Common Multiple (LCM), which of these two numbers is 4.
3/4 and 2/4 Then you would multiply the denominator the same amount you multiplied the denominator.
and voila! 3/4 and 2/4 have matching denominators

Hey there!
For this problem, I believe that they're saying that a number divided by –2/3 is equal to –9/10.
We can tell immediately that the mystery number is a positive number, since two negative numbers being divided by one another will give you a positive quotient.
For actually solving the problem, you can refer to what you learned (presumably) a while ago about number families:
9 / 3 = 3
3 * 3 = 9
Using that, you can assume the following will get you your mystery number:
x / –2/3 = –9/10
–9/10 * –2/3 = x
For multiplying fractions, all you need to do is multiply the numerators and the denominators together. The denominator doesn't have to be the same on both fractions.
(–9/10) * (–2/3) = 18/30 = 9/15
To check, all you have to do is remember the original problem:
(9/15) / (–2/3) =
(9/15) * (–3/2) = –27/30 = –9/10
When multiplying fractions, remember that the negative applies to both the denominator and numerator. Also, when dividing fractions, you will multiply the (untouched) first fraction by the second fraction with the numerator and denominator, aka the reciprocal.
Hope this helped you out! :-)
