cheap answer is, you <u>multiply one fraction by the other's denominator</u>, so let's do that with both of these fellows.

Answer: +24
Step-by-step explanation: To multiply (-8)(-3), remember that a negative times a negative is always a positive. So (-8)(-3) is +24.
I do not know the answer but download the app called Photomath and it will give you the answer
So to convert from leiters per minute to milileters per second
lieters=L
milileters=ml
minute=M
second=S
L/M=liters pre minute
ml/s=milileters per second
so to convert, just conver them seperately first
L=1000ml
M=60S
therefor
conversion factor for M to S=
M times 60S/1M=minutes
conversion factor from L to ml=
L times 1000ml/L
so basically to convert, just multiply the equations gotether
L/M times 1000ml/L times M/60s (we flipped the M to S equation since M is on the bottom) =L/M times 1000/60=L/M times 100/6=L/M times 50/3
if you have 50 liters per minute than
50/1 times 50/3=2500/3=833.33333 ml per second
