**Shelby**, Saturday, October 13, 2012 at 10:08pm128=x+16

128= number of total students.

X= the number of boys

so, 16+X because there are 16 more girls than boys...

so subract 16 from 128 which equals 112

so the number of boys is 112 and the number of girls is 112+16

**Amber**, Wednesday, October 22, 2014 at 2:16amSubtract 16 from the number of all students. 128 - 16 = 112. Divide 112 by 2 = 56. There are 56 BOYS and 56 + 16 = 72 GIRLS

**Sandy**, Wednesday, February 11, 2015 at 12:40amLet boys=x and girls=x+16:-

boys + girls =218

x + (x+16 =218

2x + 16 =218

x = (218-16)/2

= 101

Hence boys =101 and girls =101+16

Hope this helps
