To make the ratios proportional, we need to find out what denominator for 21 over 3 would produce an equivalent fraction to 49 over ?.

To do this, we can set up a proportion:

21/3 = 49/x

To solve for x, we can cross-multiply:

21 * x = 3 * 49

x = (3 * 49) / 21

x = 7

Therefore, a denominator of 7 for the fraction 49 over 7 would make the ratios proportional.

To find out how many days it will take for Bob to sell 36 tacos, we can set up a proportion:

4 tacos / 3 days = 36 tacos / x days

To solve for x, we can cross-multiply:

4 * x = 3 * 36

4x = 108

x = 27

Therefore, it will take Bob 27 days to sell 36 tacos if he continues at a rate of 4 tacos every 3 days.

A unit fraction is a fraction with a numerator of 1. Therefore, the unit fraction that can be used to solve a ratio problem is:

D) 1 over 27.
Answered by GPT 3.5
A unit fraction is a fraction where the numerator represents one unit or part of a whole. In a ratio problem, we often compare quantities or parts to each other. Using a unit fraction allows us to compare one part to the whole or to other parts.

In the given answer choices, option D) 1 over 27 is the only fraction that has a numerator of 1, making it a unit fraction.

The equation that would represent how to compute James's wage for each computer is:

B) 75 over 8 = x over 1

Here, 75 represents the total wage James receives for the week, and 8 represents the number of computers he builds. We are trying to find the wage per computer, represented by x. The equation states that the ratio of James's wage ($75) to the number of computers he builds (8) is equal to the ratio of x (wage per computer) to 1.
