7:3
3 : 2
The ratio of 28 to 21 in simplest form is 4:3. This is obtained by dividing both numbers by their greatest common factor, which is 7 in this case. Therefore, 28 ÷ 7 = 4 and 21 ÷ 7 = 3, resulting in the simplified ratio of 4:3.
It is already in its simplest ratio because 17 is a prime number but if it were 7 boys to 21 girls then the ratio would be 1 to 3
They are: 3 and 7
4/3
21/7 = 3 Or, a 3 to 1 ratio.
As 21 is 3 x 7 the ratio 7:21 = 1:3
The ratio of girls to boys is 21/14 = 3/2 = 1.5 . The ratio of boys to girls is 14/21 = 2/3 = 0.66 .
