It can't be one.
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.
1/2 can't become a whole number.
Well, honey, to write 4.2 as a mixed number, you simply divide 4.2 by 1 to get 4 whole, and then you're left with 0.2. Since 0.2 is the same as 2/10, the mixed number would be 4 2/10. But if you want to simplify it, it would be 4 1/5. So there you have it, darling.
Multiply the denominator by the whole number, add the numerator and put the total over the original denominator. Reduce if possible.
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
To write a whole number as a fraction, simply place the whole number over 1. For example, the whole number 5 can be expressed as the fraction 5/1. This representation indicates that the whole number can be divided into one whole part.
The easiest way is to use the whole number as the numerator over the divisor 1.
1.25
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.
18/5 = 3.6
12/2 = 6, a whole number.
40/5 = 8, a whole number.
20/12 can not be expressed as a whole number but as a mixed number it is 1 and 2/3
