Find the sum. Write your answer in the simplest form. 2 1/2 + 5 5/8
A 7 7/8
B 7 6/10
C 7 3/5
D 8 1/8

(D) 8 1/8

Step-by-step explanation:

In solving fractions in addition or subtraction form, the easiest approach is by identify their lowest common multiple LCM

2 1/2 + 5 5/8

Let's convert the fraction to an improper fraction, so we can comfortably work with the LCM. The equation becomes:

5/2 + 45/8

The LCM here is 8.

Multiplying through by 8 becomes:

= (8) 5/2 + (8) 45/8

= (20 + 45) / 8

= 65 / 8

= 8 1/8

i will answer your question though.

i never tried church's

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
