Question

half of a certain number added to its one third gives 30.find the number

Answer 1

Answer:

36

Step-by-step explanation:

Let the number be 'x'.

The equation formed will be as follows -

1/2x + 1/3x = 30

x(1/2 + 1/3) = 30

x(3+2/6) = 30

x * 5/6 = 30

x = 30 * 6 / 5

x = 180/5 = 36

Answer 2

let the number be 'x'
so,
x/2 +x/3=30
3x+2x/6=30
5x/6=30
x/6 =6
x=6×6
x=36
the number is 36
