(I NEED A CLEAR ANSWER AND ILL MARK YOU AS BRAINLYEST)

Answer 1

Step-by-step explanation:

100:140

to write it in the simplest form you have to find the gcf of these numbers and divide both of them by the hcf = 20

=>100÷20 : 140÷20

=5 : 7

Answer 2

no. of boys : no.of girls

100 : 140

to get the simplest ratio you gotta divide both with a common factor

Because both 100 and 140 share a common factor of 20

the simplest ratio will be

100/20 : 140/20

5:7

5:7 is the simplest ratio
