Answer:
24 boys
Step-by-step explanation:
You can solve this using simultaneous equations.
You know the number of boys plus the number of girls is 52, so b + g = 52.
You also know the number of boys is 6/7 the number of girls, so b = 6/7g
Then you can substitute this into the first equation - 6/7g + g = 52, so 13/7g = 52.
Solving that equation, 52 / 13/7 = 28, so there are 28 girls.
You then work out the number of boys by doing 52- the number of girls, so 52- 28 = 24 boys
Hope this helps, let me know if you have any questions :)
