Question:-

Which arithmetic expression has a value of 8 ?

  1. 720 ÷ 9
  2. 720 ÷ 90
  3. 7,200 ÷ 9
  4. 7,200 ÷ 90

Solution:-

Let's solve and then we can find which arithmetic expression has a value of 8.

No.1:-


\sf\dashrightarrow720 / 9


\sf\dashrightarrow (720)/(9)

Cancel 720 and 9:


\sf\dashrightarrow \: \cfrac{ \cancel{720}}{ \cancel9}


\sf\dashrightarrow \: 80

This expression is equivalent to 80, not 8.

No.2:-


\sf\dashrightarrow720 ÷ 90


\sf\dashrightarrow \: (720)/(90)

Cancel 0 and 0:


\sf\dashrightarrow \: (72 \cancel0)/( 9\cancel0)


\sf\dashrightarrow (72)/(9)

Cancel 72 and 9 :


\sf\dashrightarrow \cfrac{ \cancel{72}}{ \cancel9}


\sf\dashrightarrow8

So, this expression is equivalent to 8.

Hence,


\boxed{\bf \ 720 ÷ 90} \: \rm \: has \: a \: value \: of \bf \: 8\it .
