Answer 2

Replacing Two Actions with One

To replace two actions with one, we need to find an operation that achieves the same result as performing both actions separately. Let's go through each option and determine the correct operation:

a) 2 * 3: This is a multiplication operation, which means multiplying 2 by 3. The result is 6.

b) 10 * 2: This is also a multiplication operation, which means multiplying 10 by 2. The result is 20.

c) 2 * 2 + 10: This expression involves both multiplication and addition. First, we multiply 2 by 2, which gives us 4. Then, we add 10 to the result. The final answer is 14.

d) 15 + 5 / 5: This expression involves both addition and division. First, we divide 5 by 5, which gives us 1. Then, we add 15 to the result. The final answer is 16.

e) 5 * 15 / 5: This expression involves both multiplication and division. First, we multiply 5 by 15, which gives us 75. Then, we divide the result by 5. The final answer is 15.

Therefore, the correct option is e) :5 * 15, which replaces two actions (multiplication and division) with one operation. The result is 15.
