Answer:
5/18
Step-by-step explanation:
note: 5/9 is the same as 10/18 (we get this by multiplying both numerator and denominator by 2)
hence
5/9-5/18
= 10/18 - 5/18
= (10-5) / 18
= 5/18
Answer: one number is 104, the first number is 26 and the third number is 126
How to:
Let’s say the “first number” is Y, the “second number” is X, and the “third number” is Z. This makes Y=4x and Z=x+100. Then put it into an equation to find the sum: X+4x+x+100=256. Take away 100 from both sides of the equation and combine the like terms (the X’s). That leaves 6x=156. Then divide both sides by 6 to get x alone which is x=26. That is the first number. To find Y just multiply X by 4 and that’s Y=104. And lastly add 100 to x which is Z=126.
Arrange in ascending order:-
3, 5, 23, 27, 35, 37, 45, 48, 49
There are 9 values so the median = middle 5th value
= 35 Answer
