Math Problem Statement

Write two numbers that multiply to the value on top and add to the value on bottom. The values are 30 (top) and 11 (bottom).

Solution

This is a common factor puzzle. The goal is to find two numbers that:

  1. Multiply to give the value on top (30).
  2. Add to give the value on the bottom (11).

We need to find two numbers that satisfy these conditions:

  • Their product is 30.
  • Their sum is 11.

Step-by-Step Solution:

  1. Let's list the factor pairs of 30:

    • (1, 30)
    • (2, 15)
    • (3, 10)
    • (5, 6)
  2. Now, we check which of these pairs adds up to 11:

    • 1 + 30 = 31 (No)
    • 2 + 15 = 17 (No)
    • 3 + 10 = 13 (No)
    • 5 + 6 = 11 (Yes)

Thus, the two numbers are 5 and 6.
