Answer: 7/8

Step-by-step explanation: This is a substitution problem, from the expression x + ³/₄, where x = ¹/₈, we now replace or substitute for x and then solve the expression fractionally, the expression now becomes

¹/₈ + ³/₄

Now , find the l. c. m. of the denominator 8 and 4

            1 + 6

        =  _____    

              8

          = 7/8

NOTE: To get 1 and 6, you find out how many times 8 can go in the l. c. m. and later multiplied the number of times by  the numerator which = 1.

And the number of times 4 can go in the l. c. m. (8) which is 2 times then multiplied by the numerator (3) = 6.

Adding 1 and 6 together gives 7/8.
