B 720 ÷ 90

C 7,200 ÷ 9

D 7,200 ÷ 90

Answer 1

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 .`
