Change fractions to mixed numbers

Basically, see how many times the denominator will go into the numerator. For Problem A, 3 goes into 11 three times. But you still have 2 left over. Leave these, and put the three in front. Your answer is 3 and 2/3.

B. 3 and 3/8

C. 5

D. 4 and 1/5

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
