Question

j+4 3/8=8 I looked in the book and it says 3 5/8 but don't know how to get that.

Answer 1

its like the pythagorean theory (sort of)
you have one part of the equation and the answer
j+4 3/8 plus what gives you 8?
its 3 5/8
do it like this
j=8-4 3/8
you just substitute for j

Answer 2

j + 4 3 / 8 = 8
- 4 3 / 8 -4 3 / 8
j = 3 5 / 8

Answer 3

You start with:
j + 4 3/8 = 8

To solve this problem you must move terms around to leave the variable "j" on one side by itself. Right now it has + 4 3/8 on the same side as the "j".

To move the + 4 3/8 you must do just the opposite to both sides of the equation. The opposite of "+ 4 38" is "- 4 3/8". Do this to both sides:

j + 4 3/8 - 4 3/8 = 8 - 4 3/8

+ 4 3/8 - 4 3/8 = 0 on the left side. Now you have:
j = 8 - 4 3/8

8 - 4 3/8 = 3 5/8 so j = 3 5/8

Answer 4

The first thing I would do is substract 4 3/8 from each side:

j + 4 3/8 - 4 3/8 = 8 - 4 3/8
j = 8 - 4 3/8
then I would convert the 8 to 64/8 and convert 4 3/8 to 35/8
j = 64/8 - 35/8
j = 29/8 change to mixed number
j = 3 5/8

Answer 5

j + 4 3/8 = 8

so you have "something" + 4 3/8 = 8

so you take away the 4 3/8 from the 8 and that will leave the answer

when dealing with 8ths 8/8 = 1

8 becomes 7 8/8 minus the 4 3/8

so 7 minus 4 = 3

and 8/8 minus 3/8 = 5/8

so then j = 3 5/8

to check you add 3 5/8 to 4 3/8 and get 7 and 8/8

8/8 = 1

so add 7 to 1 = 8

Answer 6

That's a pretty easy one. 4+3 = 7, you got that part, I'm sure

3/8 + 5/8 = 8/8 or 1

7+1=8

So 3 5/8 + 4 3/8 = 8

Answer 7

subtract 4 3/8 from 8

Answer 8

4 3/8 is really 35/8 right? right!

okay sooo...

8 is also know as 64/8

so you have

j = 64/8 - 35/8 = 29/8 which is the same as saying 3 5/8
