Question

-27/32 multiply 14/15 multiply by 3

Answer 1

\[-\frac{27}{32} \times \frac{14}{15} \times 3\]

right?

Answer 2

yes

Answer 3

cross multiply to get \[-9\times7\times3/16\times5=-189/80\]

Answer 4

Okay, so...
\[-\frac{27}{32} \times \frac{14}{15} \times \frac{3}{1}\]

Multiply all the numerators (all the numbers at the top)

Then multiply all the denominators (all the numbers at the bottom)

Then simplify result if possible

Answer 5

so 1134/480

Answer 6

Actually you can change that into one big fraction, then simplify elements with common factors:

\[-\frac{27 \times 14 \times 3}{32 \times 15 \times 1}\]

Answer 7

For example,
27 and 15 is reducable by common factor 3
32 and 14 are reducable by common factor 2

Answer 8

shouldndnt be 7/5

Answer 9

If you reduce 27 and 15 by common factor 3, you divide both by 3 to get 9 and 5
If you reduce 32 and 14 by common factor 2, you divide both by 2 to get 16 and 7

Then you can re-write the fraction like so:

\[\frac{9 \times 7 \times 3}{16 \times 5 \times 1}\]

Answer 10

so 189/80

Answer 11

forgot the negative, my bad.

Answer 12

so -189/80

Answer 13

Yes, correct

Answer 14

thank you

Answer 15

By the way, if you want to make a fraction like me, open equation editor and type frac{a}{b} to get: \[\frac{a}{b}\]

Answer 16

ok dear..

Answer 17

when i start a new question it does not give me that equation editor

Answer 18

You can use the equation editor here to create it, then copy and paste the tex format (include the parentheses and brackets) into the question

Answer 19

oh ok thanks
