Question

Read the passage.

Hanna and Ai-Lin had to wait in line for three hours to buy concert tickets. Then, they had to park a mile away and wait for forty five minutes to get into the stadium. Over one thousand people attended the concert!

To correct the punctuation error in the passage, the writer should hyphenate

“three hours.”
“a mile.”
“forty five.”
“one thousand.”

Answer 1

“forty five.”

Compound numbers from twenty-one to ninety-nine are written with a hyphen, so it should be “forty-five minutes.”
