Hi, I'm Ryan Ault. I'm a physicist and this is how to subtract a whole number with a fraction. Looking at an example case, we can have two minus one and three quarters. In order to subtract these, the first thing you have to do is convert this number to an improper fraction. And, the way it works is you multiply the denominator by the preceding number, and it's four times one, and you add the numerator. So, it's simply seven over four. And, now, we have two minus this improper fraction. We still can't subtract them until we convert them, so they have the same denominator. So, what we can do is multiply the first term by four over four, and it becomes eight over four. So, now, looking at this whole term, we have eight over four minus seven over four. And, now, that their denominators are identical, we can perform the subtraction and we find that it's equal to eight minus seven, over four, which is equal to one over four. So, we find that we can subtract these two numbers by converting one to an improper fraction and then, making sure the bases of the denominators match. I'm Ryan Ault. This is how to solve subtraction of a whole number with from a fraction.
