If the ratio of two numbers is 3:5 and their sum is 64, find the numbers.
24, 40
Let the numbers be \(3x\) and \(5x\). Then \(3x + 5x = 8x = 64\), so \(x = 8\).
The numbers are \(3 \times 8 = 24\) and \(5 \times 8 = 40\).
Hence, the numbers are 24 and 40.
Two numbers are in ratio 7:9, and their sum is 128. Find the numbers.
If the sum of 28 and 22 is multiplied by 8, what is the result?
