Answer:
The combined weight is 410 pounds
Explanation:
* Lets explain how to solve the question
- There are three baby giraffes at the zoo
- One weighs 148 pounds
- One weighs 125 pounds
- The other weighs 137 pounds
- We want to find the combined weight
∵ Combined weight means the sum of their weight
∴ The sum of their weight is the sum of 148 , 125 and 137
- We can find this sum by easy way if we do that:
∵ 148 = 100 + 40 + 8
∵ 125 = 100 + 20 + 5
∵ 137 = 100 + 30 + 7
-----------------------------
= 300 + 90 + 20
∵ 300 + 90 + 20 = 410
∴ 148 + 125 + 137 = 410
∴ The combined weight is 410 pounds
