Question:-
Which arithmetic expression has a value of 8 ?
- 720 ÷ 9
- 720 ÷ 90
- 7,200 ÷ 9
- 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]
