1. if a tank leaks 10 ml of fluid each hour, how long will it take to fill up a one liter jar?

1 hour
10 hours
100 hours
1,000 hours

2. match these items.

1. kg measurement of volume

2. cm2 measurement of length

3. l measurement of area

4. m measurement of mass

Q1. The answer is 100 hours

10 ml is for 1 hours
1l is for x hours
1l = 1000 ml

So, make a proportion: 
10 ml is for 1 hours
1000 ml is for x
10 ml : 1h = 1000 ml : x
x = 1h * 1000 ml : 10 ml = 100 hours

Q2. The answers are:

1. kg - measurement of mass
2. cm² - measurement of area
3. L - measurement of volume (1L = 1 dm³)
4. m - measurement of length

1.5 pounds because you put 9over 6 and then divide by 6
