Question

Okay.. now time for multiplying fractions. ): 5/2 x 16/5? Someone please explain... Do I still make the demoniaters equal?

Answer 1

cancel 5 and you will get 16/2 which is 8

Answer 2

how do you get 8 from 16/2?

Answer 3

(5/2) * (16/5)

= 80/10 = 8

Answer 4

ahh! Okay that makes sense kindof .

Answer 5

(5*16)/(2*5)

Answer 6

\[\frac 52 *\frac {16}5\]
\[\frac {16}2 *\frac {5}5\]
\[\frac {16}2 *1\]
\[\frac {16}2=8\]

Answer 7

you don't need to as it is multiplication and not addition or subtraction.
you can cancel 5 in the numerator with the 5 in the denominator.
after this you will be left with 16/2 which is 16 divided by 2.
Since 2*8=16
therefore 16/2=8.

Answer 8

alright that makes sense. But what about division? like.. 6/5 divided by 3/5? can you cancel out the 5s again?

Answer 9

you can cancel out the 1/5s

Answer 10

6/5 divided by 3/5 can be written as (6/5)*(5/3).
therefore you can cancel the 5's and the answer will be 6/3=2.

Answer 11

\[\frac{6*\cancel{\frac15}}{3*\cancel{\frac 15}}=\frac 63\]

Answer 12

alright, thanks! It makes sense.
