7:12
21/36 in lowest term is 7/12. Multiply both, the numerator and the denominator, by the same number in order to obtain equivalent fractions.
The ratio of 12 to 36 can be expressed as 12:36. To simplify this ratio, divide both numbers by their greatest common divisor, which is 12. This results in a simplified ratio of 1:3.
36 out of 100
It is 36/1.
3 feet = 36 inches so a ratio which uses the same units of measurement for both measures, would be 36:24 which is equivalent to 3:2
21/36 in lowest term is 7/12. Multiply both, the numerator and the denominator, by the same number in order to obtain equivalent fractions.
It is: 9 to 16

The ratio, as a fraction, is 7/12. The two steps are: -- Convert all units to inches (1 foot = 12 inches, so 3 feet = 36 inches) -- Reduce the ratio 21/36 (the numbers 21 and 36 have a GCF of 3) 21 divided by 3 = 7 36 divided by 3 is 12 21/36 = 7/12

So, I can't give you the answer with the appropriate formulas or w/e but this is how I figure it out in my headFind the ratio between the yard stick and it's shadow36/21 = 1.71This means that object creating the shadow is 171% taller that its shadow is longFind the amount of inches in 168 feet (this is to be more accurate with your answer)168 * 12 = 2016 inchesMultiply the previous number by the ratio found before2016 * 1.71 = 3447.4 inches (or 287.3 feet)If a 36 inch yardstick casts a 21 inch shadow, a building whose shadow is 168 feet is 287.3 feet talls'howyagottadoitboyyiieAnother answer:Using trigonometry will give you a more accurate answerTangent ratio = opposite (the yardstick) divided by the adjacent (yardstick's shadow)Tangent ratio = 36/21 = 12/7 in its lowest termsNow rearrange the formula to find the height of the buildingTangent ratio*adjacent (the building's shadow) = opposite (the building)12/7*168 = 288The height of the building is 288 feet.
You can write this as 51:36.Note: You can simplify ratios the same way you simplify fractions; that is, if you find a number that is a factor of BOTH numbers, you can divide both numbers by that factor, to get an equivalent ratio.
9/12 is the same as 27/36
7 + 5 = 12.36/12 = 3so you multiply each number by 3 and get a ratio of...21:15
The ratio of 12 to 36 can be expressed as 12:36. To simplify this ratio, divide both numbers by their greatest common divisor, which is 12. This results in a simplified ratio of 1:3.
Convert both to the same measure, and you have your answer. 4 feet is 48 inches, so it could be 48:36. But 36 inches is also 3 ft, so a simpler ratio would be 4:3.
