Hold on ! It's not as bad as you think.
The denominators you have are 8 and 9 .
Those numbers have no common factors, so their product
is their lowest common multiple.
For a common denominator, you should use (8 x 9) = <em>72 .</em>
5 sets with 8 left over because 50/10 is 5. 8 cant go into 10 so 8 is left over

Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.
