### Re: Ratios: 2 drinks made w/ concentrate & water

1st: 2 cans drink to 5 cans water: drink/water=2/5=0.4
2nd: 500mL drink to 1000mL water: drink/water=5/10=1/2=0.5
0.5 is bigger

### Re: two numbers. The difference is 24 and the sum is 60.

So 60 - 24 = 36, 36/2 = 18, 18 + 24 = 42

checking: 42 - 18 = 24 and 42 + 18 = 60

the numbers are 18 and 42

Thanks
