What is the least common denominator of the fraction 3 x over x plus 1 plus the fraction x plus 1 over 2 x plus the fraction 5 o
Hoochie [10]
3x/(x+1) + (x+1)/(2x) + (5/x)

To find the least common denominator, we multiply the denominators that cannot factor into eachother. x, the denominator in 5/x, fits into 2x, so we do not need to multiply this number.
Therefore, the least common denominator is:
2x(x+1) 

The first term will be multiplied by 2x/2x
The second term will be multiplied by (x+1)/(x+1)
The third term will be multiplied by 2(x+1)

Alexeev081 [22]
He is leaving 20% tip of the bill of $58

20% extra

So total amount = 100% + 20% = 120%

120% of 58

(120/100) * 58

1.2 * 58

= 69.6

So total amount Alexi needs to pay = $69.60
