You're welcome.

To find the ratio of the total number of light bulbs to the number of bulbs that are burned out, we need to divide the total number of bulbs by the number of burned out bulbs.

First, let's calculate the total number of bulbs that are not burned out. We start with 50 light bulbs and subtract the 8 burnt-out bulbs, which gives us 50 - 8 = 42 bulbs not burned out.

Now, we can write the ratio in three different forms:

1. We can express the ratio as a fraction: 42/8.
2. We can express the ratio using a colon: 42:8.
3. We can express the ratio using the word "to": 42 to 8.

Now, let's simplify the fraction to its simplest form. The greatest common divisor (GCD) of 42 and 8 is 2. By dividing both numerator and denominator by 2, we get the simplified ratio:

1. Fraction form: 42/8 = 21/4.
2. Colon form: 42:8 = 21:4.
3. "To" form: 42 to 8 = 21 to 4.

So, the ratio of the total number of bulbs to the bulbs that are burned out is 21/4, 21:4, or 21 to 4.
