Larry made 3 free throws out of 7 attempts, and

Karl made 9 free throws out of 14 attempts.

Are these ratios equivalent?

• Yes, because 7 times 2 equals 14.

• Yes, because both parts of the first ratio were multiplied by the same number.

• No, because

  3 + 7 = 10 and

  9 + 14 = 23, and those sums are not the same.

• No because 3 times 3 equals 9, but 7 times 2 equals 14; therefore both parts were not multiplied by the same number.
