Yo tengo is correct i got a 5/5 on propotions thankss
No problem! :D
1. To determine which pair of ratios form a proportion, you need to check if the ratios are equal.
- Option A: 1/6 and 4/20
To compare these ratios, you can simplify both fractions to their lowest terms. Simplifying 1/6 gives you 1/6, and simplifying 4/20 gives you 1/5. Since 1/6 is not equal to 1/5, this pair does not form a proportion.
- Option B: 7/9 and 28/36
Simplifying 7/9 gives you a fraction in its simplest form, and simplifying 28/36 gives you 7/9. Since they are equal, this pair forms a proportion.
- Option C: 14/18 and 21/27
Simplifying both fractions gives you 7/9 and 7/9. Since they are equal, this pair forms a proportion.
- Option D: 30/80 and 8/18
Simplifying 30/80 gives you 3/8, and simplifying 8/18 gives you 4/9. Since they are not equal, this pair does not form a proportion.
So the answer is: B. 7/9, 28/36 and C. 14/18, 21/27
2. To identify the pair of ratios that does not form a proportion, you need to check if the ratios are equal.
- Option A: 3/5 and 24/40
Simplifying both fractions gives you 3/5 and 3/5. Since they are equal, this pair forms a proportion.
- Option B: 30/10 and 15/3
Simplifying both fractions gives you 3/1 and 5/1. Since they are not equal, this pair does not form a proportion.
- Option C: 9/14 and 3/4
Simplifying both fractions gives you the same ratios, so this pair forms a proportion.
- Option D: 7/12 and 14/24
Simplifying both fractions gives you 7/12 and 7/12. Since they are equal, this pair forms a proportion.
So the answer is: B. 30/10, 15/3
3. To find the value of m that makes 4/16 = m/24 a proportion, you can cross-multiply.
Cross-multiply:
4 * 24 = 16 * m
Simplify:
96 = 16m
Divide both sides by 16 to solve for m:
m = 96/16
m = 6
Therefore, the value of m that makes the proportion true is m = 6.
The answer is: A. m = 6.
