Tell whether ratios form a propotion
1/4; 3/12
54/10; 81/15
18/24; 15/20
someone help me pls:(
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.

Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.
Find the value of c when g=9.
Answer:
We can use the given information to set up a system of two equations:
c = 13g + 20
c - 13g = 20
The second equation is obtained from the first equation by subtracting 13g from both sides.
To solve this system, we can use substitution.
First, we solve the second equation for c.
c = 20 + 13g
Then, we substitute this expression for c into the first equation.
20 + 13g = 13g + 20
Then, we simplify.
20 = 20
So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

Charlie bought pound of American cheese and pound of Swiss cheese. Josh bought pound of cheddar cheese and pound of jack cheese. Josh says that they bought the same amount of cheese. Is he correct? Explain.
Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.
Step-by-step explanation: It's hard to say because you would need the weight of the cheese.
