How many percentage points has the interest rate increased? (please explain how you solve this problem).
The interest rate on an auto loan was 7 7/8% last month. This month, the interest rate is 9 3/4%?
im not gonna do it for you cuz 1) you have to learn it 2) i suck at math
but i do know that to add or subtract fractions, you need to have common denominators. thats that cool number on the bottom. so you what number do you multiply 4 by to get 8? once you find that, take that number and multiply both parts of the fraction by it. 3*that number and 4* that number. so then you have a number over 8 for both fractions. then you take the 9 and the fraction minus the 7 and the fraction. thats your answer. good luck with your hw :)
