Typical algebra problem: if x is equal to 7 and y is equals to two/thirds of x what is the distance to the sun.

You made (-1 1/6) into (-1 5/6) on your third line...

2 3/8 - (-1 1/6 )

2 3/8 = 2 9/24

- (-1 5/6) = 1 20/24

-----------------------------------

3 29/24 = 4 29/24

3 13/242 3/8- (-1 1/6)

Step-by-step:

2 3/8 - (-1 1/6)

2 3/8 + 1 1/6: minus a negative converts to a plus (positive)

19/8 + 7/6: convert whole numbers to fractions and incorporate into the fractions themselves

57/24 + 28/24: convert fractions in Greatest Common Denomination (GCD)

85/24: add the fractions since they have the same denominator now

3 13/24: reduce to whole numbers with the fraction again, reduce the fraction to smallest denominator but can't be in this case because 13 is a prime number and can't be reduced.

Hope this helps.

The book is wrong, it changes the value of -1 1/6 to -1 5/6 midway through the explanation, if -1 1/6 was originally -1 5/6 in the first line then the explained answer would be correct.

2 3/8 - (-1 1/6 )

2 3/8 = 2 9/24

- (-1 5/6) = 1 20/24

-----------------------------------

3 29/24 = 4 29/24

Remember these books are written by humans, humans make mistakes, so you will find at least a couple of errors in any math book. Used to piss me off when I was trying to learn some tough theory in my college Calculus book and it had an error that slipped through the proof readers.
