1/2+1/1=2/3; THE FRACTION 2/3 is not equal to 1/2
Find a counterexample to show that the following statement is false. Adding the same number to both the numerator and the denominator (top and bottom) of a fraction does not change the fraction's value. Choose the correct answer below.
A n Ø is the empty set feedback:Remember that Ø is the symbol for the empty set. The Ø contains no elements. To find the intersection of A and Ø, look for the elements that are common to both sets.
Find the set A n Ø . u={1,2,3,4,5,6,7} a={1,4,6,7}

57 months how to solve: 12825/225=57
You have a car loan and want to know how long it will take to pay it off if you do not pay any additional amount each month. You originally had a six-year loan. How long would it take you to pay off the remaining $12,825 if you paid $225 monthly?
n+3 2n+6 2n n 0 how to solve: N is your place holder. in the directions, it says add 3, so you get n+3. Then it says double result, so you double the n and 3 and you get 2n+6. then subtract 6 from 2n+6 which is 2n then divide by 2 to get n by itself, which is n then sub by og num (n) so n-n=0
b. Represent the original number as n, and use deductive reasoning to prove the conjecture in part (a). add 3 double result sub. 6 divide by 2 sub. og num.
