subtract 1500gm from 15kg and then add the result to 16kg 750gm
Answers
Answer:
In subtraction of mass we will learn how to find the difference between the units of mass or weight. While subtracting we need to follow that the units of mass i.e., kilogram and gram are converted into grams before subtraction and then follow the simple subtraction process.
We will learn two different methods to solve subtraction using the standard unit and smaller unit of mass. Students can practice both the methods.
(i) Subtracting units with conversion into gram
(ii) Subtracting units without conversion into gram
Step-by-step explanation:
We know, 1 kg = 1000 grams
Now kg and g are converted into grams before doing subtraction and then we need to follow the simple subtraction process.
11 kg 460 g = (11 × 1000) g + 460 g = 11000 g + 460 g = 11460 grams
25 kg 765 g = (25 × 1000) g + 765 g = 25000 g + 765 g = 25765 grams
Now sum,
25765 g
- 11460 g
14305 g
= 14 kg 305 g
Therefore, 25 kg 765 g - 11 kg 460 g = 11 kg 305 g
Method 2 (without conversion into gram):
Here kg and g are arranged in different columns and then added like ordinary numbers.
Follow the steps:
(i) kg and g are arranged in columns
(ii) 765 g - 460 g = 305 g
(iii) 25 kg - 11 kg = 14 kg
kg g
25 765
- 11 460
14 305
= 14 kg 305 g
Therefore, difference of 11 kg 460 g from 25 kg 765 g = 14 kg 305 g
2. Subtract 24 kg 565 g from 45 kg 225 g
Solution:
Method 1 (with conversion into gram):
We know, 1 kg = 1000 grams
Now kg and g are converted into grams before doing subtraction and then we need to follow the simple subtraction process.
24 kg 565 g = (24 × 1000) g + 565 g = 24000 g + 565 g = 24565 grams
45 kg 225 g = (45 × 1000) g + 225 g = 45000 g + 225 g = 45225 grams
Now sum,
45225 g
- 24565 g
20660 g
= 20 kg 660 g
Therefore, 45 kg 225 g - 24 kg 565 g = 20 kg 660 g
Answer:
30 kg 250gm
Step-by-step explanation:
15kg = 15000gm
so,. 15000gm- 1500gm
= 13500gm
16 kg 750gm = 16750gm
so,. 13500gm + 16750gm
= 30250gm
= 30 kg 250 gm
