Simply multiply the entire expression by any number (preferably a positive integer) to obtain an equivalent ratio.
2 : 5 = 2 x 2 : 5 x 2 = 4 : 10
2 : 5 = 2 x 3 : 5 x 3 = 6 : 15
2 : 5 = 2 x 4 : 5 x 4 = 8 : 20.........and so on.
x = 16 and 2/3 or 16.666666.....recurring decimal Ratios have been increased by 3 and 1/3
You can produce an infinite number of ratios that are equal 3:7. You can do this by simply multiplying both 3 and 7 by the same number, so for example: 3 x 2:7 x 2 6:14 = 3:7 3 x 5:7 x 5 15:35 = 3:7

50/90, 500/900 and 55/99 are three ratios equivalent to 5/9.
No
To compare we have to calculate the ratios in simplest form. The ratios of 6 /8 =3/4.and 8/10 =4/5 . and we can say 4/5 is not equal to 3/4.
A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.

You can check this by getting common numerators or denominators for the two fractions. Common numerators: The numerators are 3 and 5. These can be multiplied together to get 15, the new numerator. To get the numerator to equal 15, 3/2 is multiplied by 5/5 to become 15/10. To get the numerator to equal 15, 5/3 is multiplied by 3/3 to become 15/9. 15/9 does not equal 15/10. Common denominators: The denominators are 2 and 3. These can be multiplied together to get 6, the new denominator. To get the denominator to equal 6, 3/2 is multiplied by 3/3 to become 9/6. To get the denominator to equal 6, 5/3 is multiplied by 2/2 to become 10/6. 9/6 doesn't equal 10/6. Both methods show that 3/2 does not equal 5/3.
