 How many ones are there in the number 9?

# Level 3-4 Numbers - Place Value

If you want to understand the values of numbers then you'll need to know the values of the places in them. In KS3 Maths you should be well familiar with place values so this quiz will test just how much you've learned.

We know the value of a digit changes with its position in a number relative to the decimal point. Before the decimal we have ones, tens and hundreds, and after we have tenths, hundredths and thousandths. We also use place holders. Zeros at the end of a number are place holders. They come after another number, a 1 for example, to show whether it is worth 10, 100 or 1,000. The number 648.937 is 6 hundreds (600) + 4 tens (40) + 8 ones (8) + 9 tenths + 3 hundredths + 7 thousandths.

The following quiz will recap the subject of place values. Take your time and read each question carefully before choosing your answers. Good luck!
