C.       How to say fraction
Generally, we can say a fraction sign (ex:  a:b or a/b) with word ‘over’, for example:
a.  37:5 , it should be said as ‘thirty seven over five’.
b.3:7 , it should be said as ‘three over seven’

Note :  The upper part of fraction called a numerator, the lower part of a fraction called a denominator.

c. Some fractions already have a designated name, but the value of the numerator should not more than the value of the denominator.
Example:
½ is half
x:3   is x-third; one-third, two-thirds, not five-thirds
x:4  is x-quarter; one-quarters, three-quarters, not seven-quarters
x:5  is x-fifth; one-fifth, two-fifths, three-fifths, not nine-fifths

D.       How to say mathematical expression

Math expression
English expression
25 + 352 = 377
Twenty five plus three hundred and fifty two is three hundred and seventy seven
45 – 56 = -11
Forty five minus fifty six is negative eleven
3 × 7 = 21
Three multiplied by seven is twenty one
24 : 6 = 4
Twenty four divided by six is four
43 64
Four raised to the power of three is sixty four or four cubed is sixty four
Ö625= 25
The square root of six hundred and twenty five is twenty five
3Ö64 = 4
The cube root of sixty four is four or the third root of sixty four is four
3Ö32 = 2
The fifth root of thirty two is two
x + y = 12
x plus y is twelve
x = y – 10
The value of x is equal to the value of y minus t
y + 3
The value of x is less than the value of y plus three
