Answer 2

Step-by-step explanation:

Let the required number be x.

Atq,

$\dashrightarrow {\sf{ \dfrac{2}{3} x = 280} }$

$\dashrightarrow{\sf{x = 280 \div \dfrac{2}{3} }}$

$\dashrightarrow{\sf{x = \cancel{280 }^{140}\times\dfrac{3}{ \cancel{2}}_1 } }$

$\dashrightarrow {\bf{ \underline{x = 420} }}$

$\huge{\therefore}$The required number is 420.
