Question

Help!! Can someone help me solve.

-5/2(1/4)+7/8/5/6

Answer 1

-5/2(1/4) + (7/8) / (5/6)
- 5/8 + (7/8) / (5/6)
-5/8 + 7/8 * 6/5
-5/8 + 42/40
-25/40 + 42/40
17/40 ==> I got this

Answer 2

Ugh sigh, its saying it \[\frac{ 29 }{ 42 }\]

Answer 3

is the problem : -5 / (2 * 1/4) + (7/8) / (5/6)
or
(-5/2)(1/4) + (7/8) / (5/6)

Answer 4

@whpalmer4 .....I do not see what I did wrong ?

Answer 5

uh, could you draw the problem, or use the equation editor button? I have no idea how to interpret this properly...

Answer 6

I don't either :-(

Answer 7

but you see it on the page in your book or problem set or screen, and I'm sure it doesn't look exactly like -5/2(1/4)+7/8/5/6 there.

Answer 8

How about:

\[-\frac{ 5 }{ 6 }\left(\begin{matrix}\frac{ 1 }{ 2 } \\ \end{matrix}\right)+\frac{ 7 }{ 9 }\div \frac{ 5 }{ 6 }\]

Answer 9

Sorry I never used the equation options before

Answer 10

I got this wrong as well I thought the answer was 67/72

Answer 11

Okay, here is the problem that gives that result :-)

\[-\frac{5}{6}\left(\frac{1}{4}\right) + \frac{7}{9}/\frac{5}{6}\]

Answer 12

oh, wait, this gives 29/40, not 29/42, could you check to make sure of the correct answer?

Answer 13

It says correct answer is \[-\frac{ 19 }{ 60 }\]

Answer 14

shout I'm sorry guys the -5/6 should be -5/2

Answer 15

to find the least common denominator, write each denominator as a product of primes:

12 = 2*2*3 = 2^2*3
45 = 3*3*5 = 3^2*5

the LCD will be the highest power of each term found: 2^2*3^2*5 = 180

Answer 16

-5/2(1/2) + (7/9) / (5/6)
-5/4 + 7/9 * 6/5
-5/4 + 42/45
-225/180 + 168/180
- 57/180

Answer 17

I'm trying to figure out how the correct answer is -19/60

Answer 18

-57/180 reduces to -19/60

Answer 19

19*3 = 57

Answer 20

Okay

Answer 21

Thank you guys for your help. I going to bed :-)

Answer 22

night - night :)
