Assuming you want the fractional part of the area, ....
area of whole paper = 9*12 inches^2 = 108 inches^2
area of typed section = 7*9 = 63 inches^2
typed section / whole sheet = 63/108 = 7/12
area of whole paper = 9*12 inches^2 = 108 inches^2
area of typed section = 7*9 = 63 inches^2
typed section / whole sheet = 63/108 = 7/12
The sheet of paper is 9 inches by 12 inches, but we have a 1 inch margin on each side, so the actual typing area will be (9 - 2) inches by (12 - 2) inches.
That gives us a typing area of 7 inches by 10 inches. However, we also have a 1 1/2 inch margin on top and bottom, so we need to subtract that too.
Subtracting the top and bottom margins, the typing area is now 7 inches by (10 - 3) inches, which simplifies to 7 inches by 7 inches.
The fractional part of the page used for typing, therefore, is 7 inches by 7 inches out of the original 9 inches by 12 inches sheet.
To find the fractional part, we divide the typing area (49 square inches) by the total area of the page (108 square inches):
Fractional part = 49 square inches / 108 square inches.
Hence, the typing area accounts for about 45.37% of the whole page, or approximately 23/51.
Voila! A fraction has been discovered in the realm of typewriters!
The total area of the page is given by the dimensions of the paper, which are 9 inches by 12 inches. That gives a total area of:
9 inches x 12 inches = 108 square inches
To find the area used for typing, we need to subtract the margins from the total area:
1 inch margin on each side = 1 inch x 2 = 2 inches
1 1/2 inch margin on top and bottom = 1 1/2 inch x 2 = 3 inches
So, the total area used for typing is:
(9 inches - 2 inches) x (12 inches - 3 inches) = 7 inches x 9 inches = 63 square inches
To find the fractional part, we divide the area used for typing by the total area of the page:
63 square inches / 108 square inches = 7/12
Therefore, the fractional part of the page used for typing is 7/12.
First, let's calculate the total area of the paper:
Total Area = Length x Width
Total Area = 9 inches x 12 inches
Total Area = 108 square inches
Next, let's calculate the area of the margins:
Top Margin = 1.5 inches
Bottom Margin = 1.5 inches
Left Margin = 1 inch
Right Margin = 1 inch
Area of Margins = (Top Margin + Bottom Margin) x (Left Margin + Right Margin)
Area of Margins = (1.5 inches + 1.5 inches) x (1 inch + 1 inch)
Area of Margins = 3 inches x 2 inches
Area of Margins = 6 square inches
Finally, let's subtract the area of the margins from the total area to find the area used for typing:
Area used for Typing = Total Area - Area of Margins
Area used for Typing = 108 square inches - 6 square inches
Area used for Typing = 102 square inches
Now we have the area used for typing. To calculate the fractional part, we need to divide the area used for typing by the total area:
Fractional part = Area used for Typing / Total Area
Fractional part = 102 square inches / 108 square inches
Simplifying the fraction, we get:
Fractional part = 17/18
Therefore, the typist used 17/18 of the page for typing.
