In a certain classroom, the ratio of boys to girls is 2 to 1. If there are 39 students in the classroom, how many are boys?
1 answer:
Answer:
26 boys
Step-by-step explanation:
boys : girls = 2 : 1
If girls = x, than boys = 2x.
Altogether girls and boys = (x+2x) = 3x
Altogether girls and boys = 39
3x = 39
x = 39/3 = 13 (girls)
2x = (2*13) = 26 (boys)
