Question

Find the value of $68.4\div6$68.4÷​6.

 

Remember!

When we are dividing, we always start with the digit that is farthest to the left, then continue to divide each digit to the right moving across the decimal to units, tenths and so on if necessary.

The place values of the number being divided and the result of the division should line up.
