Question

Rebecca had nine-tenths of a yard of ribbon. Then she gave seven-twentieths of a yard to a friend. How much does she have left? Explain

Answer 1

Again, there is a problem with the bot's answer, it is WRONG again.

9/10 - 7/20 = 11/20 , not 6/10

Answer 2

[AI-generated answer — Bot]

Rebecca has six-tenths of a yard of ribbon left after giving seven-twentieths of a yard to her friend. This can be calculated by subtracting seven-twentieths (7/20) from nine-tenths (9/10). The answer is six-tenths (6/10) of a yard.
