A medium water hose can fill a pool in 30 minutes. A larger water hose can fill the same pool in 20 minutes. If both hoses are turned on at the same time, how long will it take to fill the pool? What equation can be used to solve this work problem?

How many minutes will it take both hoses to fill the pool?

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
