You can't express 23/8 as just one whole number; the result is not integral. The nearest you can come is "2 with a remainder of 7".
No, it is a fraction. It is four tenths which would also be 40%, so it is less than one and not a whole number.
152/1 = 152, a whole number. You could write it as 151 and 1/1, but it's kind of pointless.
4 over 5 is not a whole number and so it cannot be expressed as a whole number.
1/2 can't become a whole number.
13/12 is not a whole number and so you cannot write it as a whole number.
To write a whole number as a fraction, you take the whole number over "one". 460/1 460 over 1
1.25
The easiest way is to use the whole number as the numerator over the divisor 1.
7/4 is not a whole number, and thus cannot be written as such. It can, however, be written as a mixed number. In this case, it would be written as 4 3/4.
91/1 = 91, a whole number. You could write it as 90 and 1/1 but that would be pointless.
Since 52 is not divisible by 7, 52 over 7 is a mixed fraction. It cannot be written as a whole number for the simple reason that it is not a whole number.
40/5 = 8, a whole number.
12/2 = 6, a whole number.
18/5 = 3.6
20/12 can not be expressed as a whole number but as a mixed number it is 1 and 2/3
100/5 becomes 20, a whole number.
