Answers
Answer:
1. Add 3 l 600 ml and 6 l 300 ml
Solution:
Method 1 (with conversion into milliliters):
We know, 1 liter = 1000 milliliters
Now liter (l) and milliliters (ml) are converted into ml before doing addition and then we need to follow the simple addition process.
3 l 600 ml = (3 × 1000) ml + 600 ml = 3000 ml + 600 ml = 3600 milliliters
6 l 300 ml = (6 × 1000) ml + 300 ml = 6000 ml + 300 ml = 6300 milliliters
Now sum,
3600 ml
+ 6300 ml
9900 ml
= 9 l 900 ml
Therefore, 3 l 600 ml + 6 l 300 ml = 9 l 900 ml
Method 2 (without conversion into milliliters):
Here l and ml are arranged in different columns and then added like ordinary numbers.
(i) l and ml are arranged column-wise
(ii) 600 ml + 300 ml = 900 ml
(iii) 3 l + 6 l = 9 l
l ml
3 600
+ 6 300
9 900
= 9 l 900 ml
Therefore, sum of 3 l 600 ml and 6 l 300 ml = 9 l 900 ml.
2. Add 5 l 725 ml and 8 l 450 ml
Solution:
Method 1 (with conversion into milliliters):
We know, 1 liter = 1000 milliliters
Now liter (l) and milliliters (ml) are converted into ml before doing addition and then we need to follow the simple addition process.
5 l 725 ml = (5 × 1000) ml + 725 ml = 5000 ml + 725 ml = 5725 milliliters
8 l 450 ml = (8 × 1000) ml + 450 ml = 8000 ml + 450 ml = 8450 milliliters
Now sum,
1
5725 ml
+ 8450 ml
14175 ml
= 14 l 175 ml
Therefore, 5 l 725 ml + 8 l 450 ml = 14 l 175 ml
Method 2 (without conversion into milliliters):
Here l and ml are arranged in different columns and then added like ordinary numbers.
(i) l and ml are arranged column-wise
(ii) 725 ml + 450 ml = 1 l 175 ml.
175 ml is placed under ml. 1 l is taken in l column.
(iii) 1 l + 5 l + 8 l = 14 l
l ml
1
5 725
+ 8 450
14 175
= 14 l 175 ml
Therefore, sum of 5 l 725 ml and 8 l 450 ml = 14 l 175 ml.

3. Add 17 l 387 ml, 7 l 750 ml and 9 l without conversion into milliliters
Solution:
Without conversion into milliliters here l and ml are arranged in different columns and then added like ordinary numbers.
(i) l and ml are arranged column-wise
(ii) 387 ml + 750 ml = 1 l 137 ml.
137 ml is placed under ml. 1 l is taken in l column.
(iii) 1 l + 17 l + 7 l + 9 l = 34 l
l ml
2 1 1
17 387
7 750
+ 9 000
34 137
= 34 l 137 ml
Therefore, sum of 17 l 387 ml, 7 l 750 ml and 9 l = 34 l 137 ml.
