I can't remember(nor do i want to) how to add/subtract fractions and mixed numbers. One of you nice kids work these out for some old school rep. Thanks.

(-4/5) - 7/8 =

(-1/3) + 3/8 =

1/3 - (-5/3) =

9/5 + (-4/3) =

(-10/7) + 1/6 =


Show your work... :chuckles:
 
have to make them all the same common denominate first, then do the simple math.

(-32/40) - (35/40) = -67/40 or -1 27/40

(-8/24) + 9/24 = 1/24

1/3 + 5/3 = 6/3 or 2

Have to find the Least Common Denominator:

(-4/5) - 7/8 turns into (-32/40) - 35/40 = -67/40 = -1 27/40

(-1/3) + 3/8 turns into (-8/24) + 9/24 = 1/24

1/3 - (-5/3) = 1/3 + 5/3 = 6/3 = 2

9/5 + (-4/3) turns into 27/15 + (-20/15) = 7/15

(-10/7) + 1/6 turns into (-60/42) + 7/42 = - 53/42 = -1 11/42

Rather simple once you get the hang of it to do it in your head.

(-1/3) + 3/8 = x

common denomenator between 3 and 8 is 24

-1 x 8 = ? (you're multiplying the other base in 3/8 (the #8) by the top # in -1/3 (I forget the name of that).

3 x 3 = ?

-8/24 + 9/24 = x

x = 1/24
 
No thanks needed, just some free nachos next time you are in phoenix area.

The good news is Big Max has the money to pay for a tutor when little max starts calculus.

You know Big Max is a job creator. :chuckles:

He stayed home sick. Doesn't have math book for me to re-teach myself. Math sheets due tomorrow...last day before break. :chuckles:


You guys are the best!!!! Thanks!

By the looks of your math memory and what your son is learning, you are about 2 or 3 years away from not having a prayer to reteach yourself, ie your son is on his own or needs a tutor. Math is my thing, so this was easy, but my third grade daughter was shocked when she figured out she is already a better speller than I am.
