What percent of 90 is 50
Answers
x% of 90 is 50
In math
"of" means multiply
"is" means equals
x% of 90 is 50 means
x% x 90 = 50
90x = 50
x = 50/90
x = .5555
Multiply by 100 to convert to percent (move decimal 2 places to the right)
.5555 = 55.55% = 55.6% rounded to the nearest tenth
Lets keep n as the percentage
90 and 90 cancels out
100 and 100 cancels out
n = 55.55..% ≈ 55.6%

A). Your fraction is correct. But it's not in simplest form like they want it.
Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .
B). They want the percentage that's the same as 18/45 .
Do you remember how to change a fraction to percent ?
A fraction is just a short way to say "division".
" 18/45 " means " 18 divided by 45 ".
Do the division. To change the quotient into percent, multiply it by 100 .
(Same as moving the decimal point 2 places to the right.)
Round it the nearest whole number, if it isn't already a whole number.
C). Again, your fraction is correct, but it isn't in simplest form.
Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.
D). Change this fraction to percent, just like you did for the female fraction.
(Do the division that the fraction says, and multiply the quotient by 100.)
(Round to the nearest whole number percent if it isn't already.)
You already did the technical stuff. I just added some mechanical things.

The upper and lower is determined by finding the median and making 2 groups either on the left and right of the median if the data set is a odd number, and finding median of those groups
The extreme is the minimum and maximum ranges, on how far the data set number ranges.

They are different because perpendicular lines cross one another in a specific way. The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing. It could be at any angle.
Intersecting lines= two line segments that cross at any angle.
the difference is perpendicular lines have to cross at a right angle. intersecting lines that cross at any angle
the similarity is because they both cross each other.
