Answer 3

It seems like you've provided an equation and an expression. Let's break it down step by step:

1. Equation: Y : 6 = 63 : 78 This equation represents a proportion or ratio relationship. The left side has a variable Y and the number 6, and the right side has the numbers 63 and 78. To solve for Y, you can set up a proportion:

   Y / 6 = 63 / 78

   Now, cross-multiply and solve for Y:

   Y = (6 * 63) / 78 Y = 378 / 78 Y ≈ 4.846

2. Expression: b = 100 - 68 This expression involves a subtraction operation. Simply subtract 68 from 100 to find the value of b:

   b = 100 - 68 b = 32

So, the results are:

• Y ≈ 4.846
• b = 32
