in a class there are 46 students out of them 20 are girls and 26 are boys,find ratio
which ratio do you want? girls are 20 out of total 46 so 20:46 ie 10:23 and boys are 26:46 ie 13:23. Unless you want to find the ratio between girls and boys?
the ratio between girls to boys is 20:26 =>10:13, and the ratio from boys to girls is 13:10. the ratio between boys and total number of people is 26:46 => 13:23, and the ratio between girls to the total number of people is 20:46 => 10:23
