Question

does -3/8 / (-1/6)= 9/4? explain.

Answer 1

well the sign is right..... -/- = +

now tell me, if we want to get rid of a denominator, what do we multiply by?

Answer 2

hmm.. let me think it through

Answer 3

either 2 or i thought you were suppose to, its on the top of my head but its not coming out

Answer 4

-3/8 / (-1/6)

we actually have 3 denominators to pick from, but lets use the bottom

multiply the top and bottom by 6

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

Answer 5

36(3/48) then simplify. right?

Answer 6

-6(3/8)
-------
-6(1/6) << 6/6 = 1 soo



-6(3/8)
------- which is just 6(3/8)
-1

which should be simple enough to reduce now

Answer 7

oh okay that makes sense thanks :)

Answer 8

instead of trying to remember some flip rule .... if you can clean out the fraction underneath it maths into something normal:

\[\frac{a/b}{x/y}\]
\[\frac{ya/b}{\cancel yx/\cancel y}\]
\[\frac{ya/b}{x}\]
\[\frac{y/x~a/b}{\cancel x/\cancel x}\]
\[\frac{a}{b}~\frac{y}{x}\]

Answer 9

the 'rule' is, flip the bottom and multiply

Answer 10

hmm.... so the bottom number goes on the top? is what you are saying.

Answer 11

im saying we can do the math and it works out as math is spose to work instead of trying to remember some rule that only applies to a specific situation

Answer 12

OH

Answer 13

the rule is .... flip the bottom and multiply
\[rule:\frac{a/b}{x/y}\to~\frac ab \frac yx\]

Answer 14

if you cant remember the rule .... so the math :)

Answer 15

*do the math

Answer 16

yeah i can remember the rule you just put better than the first lol

Answer 17

:) good luck

Answer 18

thank you for the help :)
