Let the number be x

So, according to question, we have

Answer 2

please mark as brailiest.
here is your answer.
Let the number be x
therefore 1/3×x=x/3
it is smaller than 2/3 by 7 means that if we add 7 on x/3 it will be equal.
x/3+7=2/3
7=2/3-x/3
7/1=2-x/3
cross multiplication
2-x=7×3
2-x=21
-x=21/2
-x=1.5
x=-1.5
