1 3/8 + 2 2/5 PLEASE HELP!!!

23/8

Step-by-step explanation:

first you want to make the 2 2/5 a complete fraction

To do this multiply the whole two by 5 then add your numerater

same with the 1 3/8 as above

by now you should have 11/8+12/5

now find a common denominater

at this point it should be 55/40+60/40

Then add them which will give you 115/40

lastly simplify and you will get 23/8

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
