Convert these unlike fractions to equivalent like fractions and add them. you must use the lcd to get the answer correct. if possible, reduce the final sum.

Your final answer would be 2/3.

The LCD would be 12.

You would have to multiply both the top and bottom of 1/4 to get the denominator to 12.

To do this, you multiply it both the numerator and denominator by 3.

This would leave you with 3/12.

The second fraction already has a denominator of 12 so we will just leave it as is.

Then you add.

3/12 + 5/12

This would give you

8/12

Then you simplify it or "reduce it" by dividing both the top and bottom by 4 to get your final answer.

2/3

The answer is c. 7 (i think) i’m almost sure though

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
