Answer:
45 copies per minute.
Step-by-step explanation:
405 / 9 = x / 1
405 × 1 = 9x
405 = 9x
405 ÷ 9 = x
45 = x
Answer:
45
Step-by-step explanation:
Let the unit of copies to printed under 1 minute be x. If the photocopier can print 405 copies in 9 minutes. Then in 1 minute, it'll take the machine 405/9= 45. So therefore x=405/9= 45 copies
