First, we would turn the mixed numbers into improper fractions. That way, it’s easier to subtract. Multiply the whole number with the denominator, then add it to the numerator.
New numbers would be 70/14 and 10/7.
Then we would make the fraction denominators the same, which means we would see which number could you multiply with 7, to get 14, which is 2.
The new fractions would be 70/14 and 20/14. After that, we would subtract the numbers. from each other.
Now that we have the same denominators, it’s much easier. 70-20=50/14. Numerator DOES NOT become zero, it stays at common denominator.
Lastly, we turn the improper fraction (50/14) to mixed number. We ask ourselves, how many of the denominator is in the numerator? The answer is 3.
The remaining is 8/14, so we write that as 3 8/14. Or three, and eight-fourteenths.
Really hope this helped! This is a simple question, so I wanted to teach you how to do this instead of just giving you the answer. Knowing how to do this is very important.
