Answer:
129/28 (4.6 approx.)
Step-by-step explanation:
The first hols 1 1/7 quarts, it is: 1 + 1/7
Using 7 as common denominator and summing:
1 + 1/7 = 7/7 + 1/7 = 8/7
The second holds 5 3/4 which is: 5 + 3/4. Using 4 as common denominator:
5 + 3/4 = 20/4 + 3/4 = 23/4
Now we need to know how much greater is 23/4 than 8/7. For comparing them we need to set them to a common denominator. The easiest way is use a number that is multiple of both, 4 and 7, lets us 28. We need to multiply the numerators by the number that, multiplied by denominators gives us 28. For the first is 4, and for the second 7.
8/7 = (8*4)/7*4=32/28
23/4= (23*7)/4*7 = 161/28
Now, we only have to subtract:
23/4 - 8/7 = 161/28 - 32/28 = 129/28
So, the second container has 129/28 more quarts of water (approx. 4.60) than the first.
