Let me teach u a trick :
From now on if u see any number divided by 5 , multiply it by 2 then put a dot on the left side of the first digit from right to left look :
[tex]42 \div 5 = [/tex]
[tex]42 \times 2 = [/tex]
[tex]84 = [/tex]
[tex]8.4[/tex]
Another example :
[tex]73 \div 5 = [/tex]
[tex]73 \times 2 = [/tex]
[tex]146 = [/tex]
[tex]14.6[/tex]
Your turn :
[tex]54 \div 5 = ?[/tex]
