Chukwu, Abdul and kunle are to share $142
This means that 
Abdul gets $11.00 less than Chukwu
This means that:

$7.00 more than Kunle.

Answer:
Step-by-step explanation:
Mean: You just add them altogether then divide the sum by how many numbers there are
Median: You put all the numbers from least to greatest then cross one off on the left and do the same on the right and repeat until there is either one or two numbers left if there are two number then you find the mean of those two numbers, but if you only have one number left then that is your answer
Mode: You find which number is the most common for enstance if there are two 3 and one 4 then 3 would be your answer because there are more 3 than 4
Range: You take the highest number and the lowest number of the set and subtract them and then you have your answer
7/2x is ur answer since the denominator is the same so you just add the numerators together
