Answer 1

Answer:

Step-by-step explanation:

Let one number be x.

Then the other number will be 4500 - x.

Given that 10% of one number if 12.5%of the other.

10% of x = 12.5% of (4500 - x)

10/100 * x = 12.5/100 * (4500 - x)

x/10 = 2.5/20(4500 - x)

x = 25/20(4500 - x)

20x = 25(4500 - x)

20x = 112500 - 25x

20x + 25x = 112500

45x = 112500

x = 112500

x = 2500.

Therefore the 1st number = 2500.

                        2nd number = 4500 - 2500

                                              = 2000.

Verification:

2500 + 2000 = 4500

4500 = 4500

Answer 2

Answer:

A problem-solving strategy is a plan of action used to find a solution. Different strategies have different action plans associated with them (table below). For example, a well-known strategy is trial and error. The old adage, “If at first you don't succeed, try, try again” describes trial and error.
