Answer 2

Changing the Value of the Expression 3.6ab

To change the value of the expression 3.6ab when the value of a is decreased by 2 times and the value of b is increased by 3 times, we can follow these steps:

1. Initial Expression: The initial expression is 3.6ab.

2. Change in Value of a: If the value of a is decreased by 2 times, the new value of a becomes 0.5a.

3. Change in Value of b: If the value of b is increased by 3 times, the new value of b becomes 3b.

4. New Expression: Substituting the new values of a and b into the initial expression, we get the new expression as 3.6(0.5a)(3b).

5. Simplify the Expression: Simplifying the new expression, we get 5.4ab.

Therefore, the new value of the expression 3.6ab, when the value of a is decreased by 2 times and the value of b is increased by 3 times, is 5.4ab.
