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 for
ty 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.”
The right answer would be the third choice - forty five. We use hyphens for words in phrases like ex-boyfriend and non-alignment. In the case of numbers, all two-word numbers from twenty-one to ninety-nine must be hyphenated.
