Sometimes the information must be extremely accurate.
When we deal with numbers, we also use:
a) Decimals, such as 6.43 and we read six point four-three, or 9.02 and we read nine point 0 (oh) two. In English we use a full stop (.) and not a comma (,) for decimals. When the numbers refer to money, 15.30, we say fifteen pounds thrity.
b) Percentages, such as 25% and we read twenty-five percent, or 3% and we read three percent.
c) Fractions, such as 3/8 we read as three-eighths or 4/9 we read as four-ninths.
But look at these: ¼ we read as one- quarter – ½ we read as one –half-1/3 we read as one – third.
As you can see, the top number is read as cardinal number. The bottom number is read as an ordinal number.
d) The information about years is also read in a special way. We say: 1675-sixteen seventy-five, or 1984 – nineteen eighty-four.
But in the new millennium we read the year as 2000 two thousand, or 2003 two thousand and three. Probably from the year 2010onwards, we will say two thousand and ten or maybe twenty ten, which seems more probable if we compare the other dates, e.g., the year1016
e) Finally, mathematical symbols are read like this: 4+5 four plus five, 7 x 3 seven times three, 8-2 eight minus two, 10:5 ten divided by five.
Squares like 52 or 82 are read five squared or eight squared.
Cubes like 73 or 93 are read seven cubed or nine cubed.
And the symbol for the square root is read for instance 4 the square root of four
