In converting the ratio in to colon form from division or fraction form, just replace the division (fraction) symbol by a colon, then simplify it, to simplify, determine the Highest Common Factor (HCF) of the terms (Just make sure that the terms are in the same units), then divide the factor to each terms.
1. 10/12 can be written as 10:12, but it can be further simplified by determining its HCF, the HCF of the terms is 2, dividing 2 to both terms will give an answer as 5:6. Same process is done to numbers 2 and 5.
