make five sets of balanced equations for the number 20:
To make five sets of balanced equations for the number 20, we need to find various combinations of arithmetic operations that equal 20. Here are five sets of balanced equations using addition, subtraction, multiplication, and division:
1. Addition:
- 10 + 10 = 20
- 5 + 15 = 20
2. Subtraction:
- 30 - 10 = 20
- 25 - 5 = 20
3. Multiplication:
- 4 * 5 = 20
- 10 * 2 = 20
4. Division:
- 40 / 2 = 20
- 100 / 5 = 20
5. Combination:
- 10 + 30 - 20 = 20
- 5 * 4 = 20
To find these equations, I started with the basic arithmetic operations and substituted numbers to balance the equation. By combining different arithmetic operations, you can create multiple balanced equations that result in the number 20.
