What are all the answers
Dom is correct!
(If they change the answers then,
B -7/15
D 1/2
C -1 1/5
D 1 1/4)
-7/9 * 3/5 = -21/45 = -7/15
nope. DOM IS CORRECT I am not.
Rei, when you multiple a positive with a positive, OR a negative with a negative, you get a positive; +x += + OR -x-=+. but when you multiple a negative with a positive, you get a negative -x+=- OR +x-=-.
so that tells us your final answer will be negative.
when you multiple two fractions, you pretty much multiple the tops together and bottoms together. 7/9 x 3/5, the top is 7*3=21. the bottom is 9*5=45. so that's 21/45. and remember from earlier, our answer has to be negative, so -21/45.
but that's not any of the choices, so let's try to reduce our fraction. go through some trial and error, and you can see both the top and bottom can be divided by 3. 21/3=7 and 45/3=15. so our reduced form is -7/15
Thats what I want to know
yep he right
I like the skatepark
@Dom is 100% correct for the Unit 4 Lesson 6 quick check!
Dom is correct for connexus!! I got 100%!!! TYSM!!!!
GOD BLESS YOU @TheRealYee
I made a 50%
Tysm I am working on math now because I hate homework but I gotta get it done to do stuff with my friends but ty!
Ty
ya dom is correct
(dtd) sorry
DDD
DEATH TO DOM
i got a 1/4
aLL DEM ANSWERS MADE ME GET A 0 JUST BECAUSE YALL DIDN'T WANNA PUT THE TEXT FORM UP THERE . AND MS SUE WRONG 2 . ITS NOT 7'15, IM GLAD I HAVE GOOD GRADES IN MATH .
