<span>A grade has 81 girls and 72 boys. The greatest split into groups that have the same ratio girls the boys as a whole grade.
=> Find how many girls are in a group that has 16 boys
Formula and Ratio:
=> 81 : 72 = x : 16 – we need to find the value of girls or the number of girls in the given ratio.
=> 16 * 81 = 1 296
=> 1 296 / 72 = 18
Therefore the value of girls numbers is 18. The new ratio will be:
18 : 16
