3. 8x3 -
How do you do 8x1/5

Step-by-step explanation:

but a way to work out fractions is that it divides

5÷8=1.6

and even if its 8 x 1 ÷5 it will give the same answer. but how to do that is :

BIDMAS Divide comes first

1÷5=0.2

8x0.2=1.6

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.

the diameter is 16 cm. are you a teacher?
