In week 6, I revised how to round off decimals.
To round off decimals, you have to look at the last number eg. 246.642 and if it is lower than four, you leave the previous number the same eg. 642.24, but if its higher than five, you make the previous number one digit larger than the last. eg. 333.456 = 333.46.
I also revised that;
- Another way of naming tenths, Hundredths, and thousandths are called decimal places.
- A place value system with 10 as a base. eg. (fractions) 1/10 1/100 1/1000
- Say the name of the digit and not the number.
