thanks for saying what I said again @phi

Answer 8

so we go 6/16 divided by 1/16

Answer 9

in this case ⅜ pizza divided by 1/16 of a minute

\[ \frac{\frac{3}{8} \ pizza}{\frac{1}{16} \ min} \]

Answer 10

3?

Answer 11

is dividing fractions equal to multiplying its reciprocal

Answer 12

of course, you can simplify that fraction by multiplying top and bottom by 16/1 or 16
\[ \frac{\frac{3}{8} \cdot 16\ pizza}{\frac{1}{16}\cdot 16 \ min} \]

Answer 13

notice the bottom is 1/16 * 16. what number is that ?

Answer 14

3/8*16/1

Answer 15

16

Answer 16

16

Answer 17

?

Answer 18

the bottom is
\[ \frac{1}{16} \cdot 16\]

Answer 19

i got 18.56

Answer 20

no.

can you simplify
\[ \frac{\frac{3}{8} \cdot 16\ pizza}{\frac{1}{16}\cdot 16 \ min} \]
what does the bottom part simplify to ?

Answer 21

1?

Answer 22

yes, so your problem is now
\[ \frac{\frac{3}{8} \cdot 16\ pizza}{1 \ min} \]
what does the top simplify to ?

Answer 23

1?

Answer 24

what is
\[ \frac{3}{8}\cdot 16\]
notice that is the same as doing
\[ 3 \cdot \frac{16}{8} \]

Answer 25

I would divide 8 into 16

Answer 26

which is 0.5

Answer 27

im so lost

Answer 28

so the answer is 3?

Answer 29

or 1?

Answer 30

you are doing the top part of
\[ \frac{\frac{3}{8} \cdot 16\ pizza}{1 \ min} \]

3* 16/8 is 3* 2

Answer 31

6

Answer 32

if arithmetic is confusing, you should review how order of operations work.

yes you get 6
⅜ * 16 is 6

so you now have
\[ \frac{6 \ pizzas}{1\ min} \]

Answer 33

In English, you would say "6 pizzas per minute"

Answer 34

oh so the answer is 6

Answer 35

not just 6

6 pizzas per minute
