Answer:
If one third of a number is added to itself and gives 10, what is the number?
Let the number be x
so, one third of the number will be x/3
Step-by-step explanation:
question states that when one third of a number is added to itself , it gives 10 which can be written as :
(x/3)+(x/1)=10
by taking the LCM on the left hand side it becomes-
(x+3x)/3=10
4x=3*10 (changing the side from left to right will also change its sign from division to multiplication)
4x=30
Answer is x=7.5
