Fraction of girls:
1 - 3 / 7 = 7 / 7 - 3 / 7 = 4 / 7
x = numbers of sudents
there are 28 girls
4 / 7 x = 28
Multiply both sides by 7
4 x = 196
x = 196 / 4 = 49
49 students there in the class.
3 / 7 of 49 are boys
3 • 49 / 7 = 21 boys
OR
boys / girls = 3 / 4
3 • 28 / 4 = 21 boys
1 - 3 / 7 = 7 / 7 - 3 / 7 = 4 / 7
x = numbers of sudents
there are 28 girls
4 / 7 x = 28
Multiply both sides by 7
4 x = 196
x = 196 / 4 = 49
49 students there in the class.
3 / 7 of 49 are boys
3 • 49 / 7 = 21 boys
OR
boys / girls = 3 / 4
3 • 28 / 4 = 21 boys
