To find 80% of a number, you can multiply the number by 0.8. Given that 20% of the number is 90, we can find the total number by dividing 90 by 0.2. This gives us a total number of 450. Therefore, 80% of 450 is 360.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
90
(18 ÷ 20) × 100 = 90 Therefore: 90%
The equator is the line of zero latitude, and it circles the 'middle' of the earth. For every latitude number between zero and 90 degrees, there are two lines with the same number ... one north of the equator and one south of it.
To find 20 percent of a number, multiply the number by 0.2. In this instance, 0.2 x 90 = 18. Therefore, 20 percent of 90 is equal to 18.
20% of 90 = 0.20 X 90 = 18.0

The median is the number which is in the middle of a data set when you order the set from smallest to largest. So this set is 45, 46, 90, 90, When you have an even number of numbers, you add the two middle number and divide by two So the median is 46+90 divided by 2.
The answer is 50, 70, 90, 20. Mean is the average. Median is the middle when put in numerical order. Mode is the number that occurs most often. Here all of the numbers occur just one time.
18 as a percentage of 90 = 100*18/90 = 20%
180 degrees - check your maths book - put to right angles back to back and take out the line in the middle what is 90 + 90?
20% of 450 is 90 So 80% of 450 will be 360
It is a point on the number line, at a distance equal to x, to the left of 90.
