Answers
Answer:
Step-by-step explanation:
1st time:
Use 5 litre and 3 litre cans to take out the water from barrel and throw the water.
Water left over in barrel = 20 - 5 - 3 = 12 litres.
2nd time:
Use 5 litre and 3 litre cans to take out the water from barrel and throw the water.
Water left over in barrel = 12 - 5 - 3 = 4 litres.
3rd time:
Use 3 litre can to take out the water from barrel.
Water left over in barrel = 4 - 3 = 1 litre.
Answer:
i can help by taking two 5 liter can and three 3 liter can.
Step-by-step explanation:
cuz if u take away 1 from 2 ur left with 19 liter.
Now u use trial and error to find out how many can u can give me. however to keep things short and simple i will just tell u how i got it.
1. first split 19 into 2 parts ( choose 10 and 9)
2. divide the first part (10) by 5 and 3 this case 5 goes into 10 2 times. therefore u give me 2 five liter can.
3. divide the 2nd part (9) by 5 and 3. in this case 5 doesn't go into nine but 3 does go into it 3 times. therefore u give me 3 three liter can.
hope this help :-)
