What denominator for 21/3=49/? would make these ratios proportional

Answer 1

To make the ratios proportional, the denominator for 21/3 must be the same as the denominator for 49/?.

Let's find the denominator for 21/3. The denominator is 3.

Therefore, the denominator for 49/? to make the ratios proportional must also be 3.

Answer 2

wrong

Answer 3

Apologies for the previous incorrect response.

To find the denominator that would make the ratios proportional, we can use the concept of cross multiplication.

The original ratio is 21/3 = 49/x

To make the ratios proportional, we need to find the value of x that satisfies the equation.

Cross multiplying, we get:

21 * x = 3 * 49

Simplifying further:

21x = 147

Dividing both sides of the equation by 21:

x = 147 / 21

x = 7

So, the denominator for 21/3 to make the ratio proportional with 49/? would be 7.

Answer 4

Nigel is selling candy bars for his outdoor club. He is averaging 4 bars every 3 days. If he continues at this rate, how many days will it take to sell his box of 36? Your answer should be a whole number.

Answer 5

To determine how many days it will take Nigel to sell his box of 36 candy bars, we can set up a proportion using the given information.

Nigel is selling an average of 4 candy bars every 3 days. We can express this as the ratio 4/3.

Let "x" represent the number of days it will take Nigel to sell his box of 36 candy bars.

Using the proportion:

4/3 = 36/x

To solve for "x," we can cross-multiply:

4 * x = 3 * 36

Simplifying further:

4x = 108

Dividing both sides of the equation by 4:

x = 108 / 4

x = 27

Therefore, it will take Nigel 27 days to sell his box of 36 candy bars.
