Answer:
e: f=3 : 7 and f : g= 2 : 3
Step-by-step explanation:
here's the answer
(1/2)+(2/3)
make bottom number same to add because
remember that we don't want to change the numbers
when you mulitply by x/x where x=x, then that is the same number
example
1/2 times 2/2=2/4
so 1/2=2/4
ok
1/2 and 2/3
bottom number is 2 and 3
2 times 3=6
so make bottom number 6
what you multiply bottom number by, you also multiply top number
1/2
2 times 3=6
1/2 times 3/3=3/6
2/3
3 times 2=6
2/3 times 2/2=4/6
now we got
=1 and 1/6

Answer:
30.4 minutes
Step-by-step explanation:
The tank already has 240L in it, so we need to fill 1000 - 240 = 760L of water.
Since the pump pumps 25L per minute, we can find how many minutes it takes to pump 760L.
760 / 25 = 30.4 minutes.
