1) You look for a common factor between the two numbers. Prime factorization can help here.
2) You divide both numbers by this factor.
Three goes into both 21 and 33.
21 to 33 can be simplified to 7 to 11.
21/7 = 3 Or, a 3 to 1 ratio.
21:6::7:2
ratio of 21 to 15
It is: 12 to 21
√33√21 = √(3x11)√(3x7) = √3√11√3√7 = (√3)^2√7√11 = 3√7√11 (or 3√77).
21 : 6factor out a 33(7 : 2)7 : 2==========simplified ratio
5 : 11
21/7 = 3 Or, a 3 to 1 ratio.
33/67 cannot be simplified.
21:6::7:2
16:21
You can simplify 33 / 55 to 3 / 5 by dividing both by 11. The ratio is 3/5.
ratio of 21 to 15
It is: 21 to 11
Expressed as a ratio in its simplest form, by dividing the antecedent and consequent by 3, 21:27 is equal to 7:9.
21 : 33 = 210 : 330 or 21000 : 33000 Its simplest form is 7 : 11
It is: 12 to 21
