Which expression has a value of 8 A 720 ÷ 9 B 720 ÷ 90 C 7,200 ÷ 9 D 7,200 ÷ 90

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:-

[tex]\sf\dashrightarrow720 \div 9[/tex]

[tex]\sf\dashrightarrow \dfrac{720}{9} [/tex]

Cancel 720 and 9:

[tex]\sf\dashrightarrow \: \cfrac{ \cancel{720}}{ \cancel9} [/tex]

[tex]\sf\dashrightarrow \: 80[/tex]

This expression is equivalent to 80, not 8.

No.2:-

[tex] \sf\dashrightarrow720 ÷ 90[/tex]

[tex]\sf\dashrightarrow \: \dfrac{720}{90} [/tex]

Cancel 0 and 0:

[tex]\sf\dashrightarrow \: \dfrac{72 \cancel0}{ 9\cancel0} [/tex]

[tex]\sf\dashrightarrow \dfrac{72}{9} [/tex]

Cancel 72 and 9 :

[tex]\sf\dashrightarrow \cfrac{ \cancel{72}}{ \cancel9} [/tex]

[tex]\sf\dashrightarrow8[/tex]

So, this expression is equivalent to 8.

Hence,

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