The width of a standard newspaper column is 2.625 in. and the length of a standard column is 19.5 in. Express the ratio of the two measurements as a ratio of whole numbers. The answer is 7/52 but I cannot for the life of me figure out how.
2.625:19.5
=2625:19500 divide by 25
=105:780 divide by 5
=21:156 divide by 3
=7:52
To determine the ratio of the width to the length of a standard newspaper column expressed as a ratio of whole numbers, we need to simplify the given dimensions.
The width of the newspaper column is given as 2.625 inches, and the length is given as 19.5 inches.
To convert the measurements into whole numbers, we can start by dividing both the width and the length by their greatest common divisor (GCD).
To find the GCD of 2.625 and 19.5, we can express both as fractions by representing them without decimals.
2.625 can be written as 2 and 5/8, which is the same as 21/8.
19.5 can be written as 19 and 1/2, which is the same as 39/2.
Now, let's find the GCD of 21 and 39.
The factors of 21 are: 1, 3, 7, 21.
The factors of 39 are: 1, 3, 13, 39.
The greatest common divisor (GCD) of 21 and 39 is 3.
Next, we divide both the width and the length by 3.
21 divided by 3 = 7
39 divided by 3 = 13
So, the simplified ratio of the width to the length is 7:13.
However, if the answer given is 7/52, it seems that there might be a mistake or misinterpretation in either the original problem or the answer provided. It is recommended to double-check the problem statement or consult the source from which you obtained the answer.
