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

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.

wrong

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.

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

Let's find the denominator that would make the ratios proportional.

21/3 = 49/x

To solve for x, we can cross-multiply:

21 * x = 3 * 49

Multiply the numbers on each side:

21x = 147

Now, divide both sides of the equation by 21 to solve for x:

x = 147 / 21

Simplify the fraction:

x = 7

Therefore, the denominator for the ratio 21/3=49/? that would make the ratios proportional is 7.

To determine the missing denominator, we need to ensure that the ratios on both sides of the equation are proportional.

In the given equation, 21/3 = 49/?.

To find the missing denominator, we can use the concept of cross-multiplication. Cross-multiplication involves multiplying the numerator of one ratio by the denominator of the other, and vice versa.

Cross-multiplying, we obtain: 21 * ? = 3 * 49.

Simplifying further, we get: 21 * ? = 147.

To find the value of ?, we divide both sides by 21: ? = 147 / 21.

Simplifying the division, we have: ? = 7.

Therefore, the missing denominator that makes the ratios 21/3 and 49/7 proportional is 7.

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.

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.
