For his reading goal this nine weeks, Jeonhee wants to read 1,000 pages. The first week he read 10 pages per day. The second week he read 15 pages per day. The third week he read 20 pages per day. How many more pages does he need to read to reach his goal?
Answers
Answer:
955
Step-by-step explanation:
So let’s start with the first one. He reads 10 pages per day on the first week. That’s 10 x 7, which he read 70 pages for the first week.
As for the second week, it’s the same: 15 x 7 = 105 pages read.
Third week: 20 x 7 = 140 pages read.
Add: 70 + 105 + 140 = 175 + 140 = 315 pages read.
Subtract: 1,000 - 315 = 685.
That’s 685 pages he still needs to read until he hits his goal. Hope this helped! :D
Eleanor and Max used two rectangular pieces of plywood, placed end-to-end, to make a long rectangular stage for the school play. One board was 6 feet long, and the other was 6 1/2
feet long. The two pieces of plywood had equal widths. The total area of the stage was 59 3/8
square feet. What was the width of the plywood?
Answers
The area is the product of length and width.
.. area = length * width
.. 61 5/8 = (7 +7 1/2) * width
.. (61 5/8)/(14 1/2) = width = 4 1/4 . . . . feet
The plywood was 4 feet 3 inches wide.

A calculator that works with fractions figures this nicely. By hand, you might compute it as
.. 61 5/8 = (8*61 +5)/8 = 493/8
.. 14 1/2 = (2*14 +1)/2 = 29/2
.. (61 5/8)/(14 1/2) = (493/8)/(29/2) = (493/8)*(2/29) = 493/(4*29) = 493/116
.. 493/116 = 4 +29/116 = 4 +29/(4*29) = 4 1/4
