This is the second in our revision sheets for dividing decimals by 10 or 100, ‘in your head’. A good understanding of place value is needed for this as there is little to do apart from move the numbers to the right. One place to the right divides by 10. Two places to the right divides by 100. Remember to put a zero in the units if there are no whole units: eg 8.7 divided by 10 is 0.87 not .87, as it would be very easy to miss the decimal and read this as 87.
