How do you subtract a whole fraction with a normal fractrion?

Answer 1

I am not quite sure what you mean with "whole fraction". If you have whole numbers, or mixed numbers, you subtract the whole part and the fractional part separately.

For example: 3 3/7 minus 1 1/7 = ???

For the whole number, subtract 3 - 1 = 2.

For the fractional part, subtract 3/7 - 1/7 = 2/7.

If the fractional part in the first number is less than the one in the second part, subtract one to the whole part, and add the equivalent fraction (equivalent to 1) to the fractional part. Here is another example:

10 1/5 minus 2 3/5 = ???

From the first fraction, subtract one to the whole part, and add 5/5 (which is equal to one) to the fractional part, so you get:

9 6/5 minus 2 3/5 = ???

Now you can continue with the subtraction as mentioned above. The result in this example is 7 3/5.

In all the examples above, I chose a common denominator; if the demoninators are not the same, converting to a common denominator is just the same as when you want to add fractions, for example.
