Answer:
1. Ratio A is equivalent to Ratio B.
2. Ratio A is not equivalent to Ratio B.
3. Ratio A is equivalent to Ratio B.
Step-by-step explanation:
1. 8 questions out of 10 (or ) and 4 questions correct out of 5 (or ) are equivalent: Dividing the numerator of each fraction by its denominator will result in 0.8: 8/10 = 0.8, 4/5 = 0.8.
2. 15 prizes won in 40 attempts (or 15/40) and 3 prizes won in 10 attempts (3/10) are not equivalent: 15/40 = 0.375, vs 3/10 = 0.3
3. 3 cats for every 6 dogs (3/6) and 1 cat for every 2 dogs (1/2) are equivalent: 3/6 = 0.5. 1/2 = 0.5
