A number, half of that number, and one fifth of that number are added. The result is 51. What is the original number?
Lera25 [3.4K]
Let the original number be ‘x’
Then half of that number= 1/2x or simply x/2
Similarly one fifth of that number = x/5
According to the question
x+x/2+x/5=51
Taking LCM
10x/10+2x/10+5x/10=51
Multiplying 10 throughout
10x+2x+5x=510
17x=510
x=510/17
Therefore x=30

Multiply me by 4 then subtract 13 if you divide me by 3 and add 17 you get 22
8_murik_8 [283]
You have to do the opposite

22-17=5
5x3=15
15+13=28
28/4=7

The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
