Lydia wrote 4 1/2 pages of her science report in one hour. What was her writing rate in pages per minute?
To find Lydia's writing rate in pages per minute, we need to divide the number of pages she wrote by the time it took her to write them.
Lydia wrote 4 1/2 pages, which can be written as a mixed number or a fraction: 4 + 1/2 = 9/2.
The time it took her to write these pages was one hour, which is equivalent to 60 minutes.
Now we can calculate her writing rate by dividing the number of pages (9/2) by the time (60 minutes):
Writing rate = (9/2) / 60
To simplify this division, we can multiply both the numerator and the denominator by 2 to get rid of the fraction:
Writing rate = (9/2) * (1/60) [multiply numerator and denominator by 1/60]
Writing rate = (9/120)
Simplifying this further, we can divide both the numerator and the denominator by their greatest common divisor (which is 3):
Writing rate = (3/40)
Therefore, Lydia's writing rate is 3/40 pages per minute.
