Answer 1

Answer:

The third number will be: 189.203

Step-by-step explanation:

Sum of three numbers: 315.655

Two numbers: 56.78, 69.672

Sum of the two numbers: 56.78 + 69.672

= 126.452

Difference between the sum of 3 numbers and the sum of the two numbers:

315.655 - 126.452

= 189.203

The third number will be 189.203
