What steps to get the principle of a 30 year loan at 5.5%?

hoa [83]

Multiply 30 -- the number of years of the loan -- by the number of payments you make each year. For example, 30 X 12 = 360. You are making 360 payments over the course of the loan. Divide your mortgage interest rate by your total payments.

Answer:

$2\dfrac{11}{12}$

Step-by-step explanation:

The first step is to ensure that all of the fractions have a common denominator.

$3\dfrac{1}{3}+\left( -2\dfrac{1}{4} \right) + 1\dfrac{5}{6}= \\\\3\dfrac{4}{12} - 2\dfrac{3}{12} +1 \dfrac{10}{12}= \\\\1\dfrac{1}{12}+1\dfrac{10}{12}= \\\\\boxed{2\dfrac{11}{12}}$
