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
Answer:
1/8
Step-by-step explanation:
1/2÷4=
1/2×1/4=1/8
Factor
(x +3) * (x -2) =0
x = -3
x = 2
