How do you express ratio?
You express ratio as a fraction. For instance, the ratio of 3 to 4 is 3/4, or .75
Is 7.5 rational or irrational?
75 times 75 = 5625 which is a rational number
Express each ratio as a fraction in simplest form read 75 pages out of 90?
5/6 or 5 to 6 as a ratio.
How do y ou find the ratio of 3 men to 4 women there are 222 men how many workers are there?
The ratio 3 to 4 can be writtem 3/4 or .75. Divide the total of men by the ratio to find how many women there are, then add the two numbers to find the total of workers: 222 /.75 = 296 women. 222 + 296 = 518 workers.
How can ratios be written?
A ratio is a comparison of two numbers. You can write a ratio in these ways: a to b, a : b, or a/b. Ratios are often written as fractions. A ratio that is expressed as a fraction is generally written in lowest terms. If the ratio involves unit of measure, you must ensure that the units are the same. Example: Write ratios in lowest terms. 20/52 = (20/4)/(52/4) = 5/13 240/200 = (240/40)/(200/40) = 6/5 There are continued ratio, or extended ratio, which relates more than two numbers. Example: The measures of the angles of a triangle are related by the ratio 3 : 4 : 5. Find the measure of each angle. Solution: The ratio 3 : 4 : 5 is equivalent to 3x + 4x + 5x. We write an equation by using, 3x, 4x, and 5x to represent the measures of the angles. The sum of the angles of a triangle is 180 degrees. So, 3x + 4x + 5x = 180 12x = 180 x = 15 Thus, the measures of the angles are 45 degrees, 60 degrees, and 75 degrees.
