Understanding the Problem
To solve the problem of adding 78 and 22 using an abacus, we first need to break down the numbers and understand their components.
Breaking Down the Numbers
- 78 consists of:
- 7 tens (70)
- 8 ones (8)
- 22 consists of:
- 2 tens (20)
- 2 ones (2)
Performing the Addition
1. Add the Tens:
- 7 tens (from 78) + 2 tens (from 22) = 9 tens (90)
2. Add the Ones:
- 8 ones (from 78) + 2 ones (from 22) = 10 ones (10)
Combining the Results
Now, we need to combine the results of the tens and ones:
- 90 (from tens) + 10 (from ones) = 100
Conclusion
Thus, the result of adding 78 and 22 on the abacus is 100. Therefore, the correct answer is option 'A'.
This addition can be visually represented on an abacus by moving the beads accordingly, verifying the accuracy of the total as each section (tens and ones) is calculated and combined.
