Starting with a full container, milk is poured three times. first, 1/2 of the milk is poured out, then 1/3 of what remains, and, finally, 1/4 of the remaining milk. after the third pouring, what fraction of the full container of milk remains

1/4 of the full container remains

Step-by-step explanation:

Step 1: Half the milk is poured out

i.e 1/2 of the milk remains

Step 2: 1/3 of what remains is poured out --> 2/3 of the remaining is not poured out.

Hence amount remaining after step 2 = 2/3 x 1/2 = 1/3 of the total

Step 3: 1/4 of what remains is poured out --> 3/4 of the remaining is not poured out.

Hence amount remaining after step 3 = 3/4 x 1/3 = 1/4 of the full container remains

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
