Answer 1

Answer:

Step-by-step explanation:

50min*9=450mins

Reduced by 5min=5*9=45min

450--45=405min

Since each period is 50min,

405/50=8.1

So there would be 8 periods...

Hope this helps!!

Answer 2

there are 9 period and of 50 min so

50*9= 450 min

5 min deducted from all period so

5*9=45 so

450 -45=405

so there were 50 min in one period

405÷ 50

= 8.1 approx 8 period
