10:30, 20:60, 15:45 are three possible ratios
4 to 10 8 to 20 20 to 100
If there is a proportion a/b = c/d, then ad = bc. Examples: 3/4 =? 5/6 3 x 6 =? 4 x 5 18 = 20 False (this is not a proportion) 16/6 =? 8/3 16 x 3 =? 6 x 8 48 = 48 True (this is a proportion)
4 to 10 6 to 15 8 to 20 10 to 25
14 out of 20 is the same proportion as 7 out of 10, so 70%.
5/10 = 1/2 write the proportion as ratios 5:10 = 1: 2 5/10 = 10/20 or 5:10 = 10:20 5/10 = 15/30 or 5:10 = 15:30
It is 3 to 5 in its simplest form
Twenty-ten-ten (20-10-10) fertilizer may or may not be suitable for gardens, depending upon the predominant form of vegetation. Lawns generally require 3-1-2 NPK (nitrogen, phosphorus, potassium) ratios, as in 30-10-20 NPK fertilizers. Trees and vegetables respectively tend to respond to 2-1-1 and 1-2-1 ratios in 20-10-10 and 5-10-5 NPK fertilizers.

10:30, 20:60, 15:45 are three possible ratios
20 to 2 30 to 3 100 to 10
If there is a proportion a/b = c/d, then ad = bc. Examples: 3/4 =? 5/6 3 x 6 =? 4 x 5 18 = 20 False (this is not a proportion) 16/6 =? 8/3 16 x 3 =? 6 x 8 48 = 48 True (this is a proportion)
no. to make a proportion both fractions must be equal.

Equivalent ratios to 4/5 can be several such as 8/10 or 16/20.
1:5, 2:10, 3:15, 4:20
