Numbers with 2 decimal places have 2 digits after the decimal point.
To round one of these numbers to the nearest 1 decimal place number think of a number line.
Numbers ending in 1, 2, 3, 4 round DOWN.
Numbers above this, those ending in 5, 6, 7, 8 and 9 round UP.
Remember that halfway numbers, such as 7.50 round UP.
Here 7.35 is between 7.3 and 7.4, but rounds up to 7.4 to one decimal place.
