**2/3 of a number is 20 less than the original number. Find the number.**

Answer:

Let the original number be x.

According to the question we can write as (2/3)x+20=x

On rearranging x-(2/3)x=20

Now taking the L.C.M of 1 and 3 is 3

(3x-2x)/3=20

x/3=20

Again by transposing x=6o

So the original number is 60

"hello students i am vita your maths
leader tutor and the today's question is
2
by 3 of a number is 20 less than
the original number find the number
first of all we let the number be
x let the number be
x and according to question it is given
that
2 by 3 of a number
2 by 3 of a number is
20 less than the original number
original number is x
minus 20 now we solve this equation 2 by
3 x
is 2 by 3 x is equal to x minus 20
when minus 20 comes to the left hand
side it becomes plus and 2 by 3 x comes
to the right hand side it becomes
minus so 20 is equal to x
minus 2 by 3 x now we take the lcm of
1 and 3 that is 3 1 threes are three so
three into x
three x minus three ones are three so
two ones are two
now we got twenty into three is equal to
three minus two
one x so twenty into three we got
sixty it means the value of x is equal
to
60 so this is our answer i hope you like
