Marcia and Tamara are running a race. Marcia has run 4 kilometers. Tamara has completed the 3/4 of the race and is 2.5 kilometers ahead of Marcia. Write an equation that represents the relationship between the distances girl has run. Let k represent the total length of the race in kilometers.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

what is the original number? you forgot to add it.
