Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute
So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.
So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.
Which would get us: Mrs. Dean: 150 wpm
Mr. Kovacs: 96(1.25)=120wpm
Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.
This should be quite easy to explain. So the first thing you want to do is multiply them. This isn't to hard if you know your times tables. Don't worry about the decimal till the end.
15.37
× 5
---------
76.85
15.37 times 5 is 76.85
Now on to the decimal. All you need to do is move it two times to the left. You see how it's in between the 5 and 3? The same goes for your answer. So it is 76.85
I hope this helped!! ^^ I can make this a little more easier to explain if you want me to just in case, ok?
The variable must be raised to the second power
So there are 2 numbers
pretend the smaller number is x, so the larger number must be 2x because it's twice as large
so 2x+x equals 54
simplifies to 3x=54
x= 18
the smaller number is 18 and the larger one is 36 (because 36 is 18 x 2)
