Answer:
70
Step-by-step explanation:
Since 2:7 is the ratio of boys to girls, that would mean that there are 2 boys to every 7 girls. 2 x 10 is what gets us to 20 and for the ratio part for girls we have to do the same thing; 7 x 10. Now the ratio is 20:70. We can make sure that we are correct by multiplying. 2 can multiply 3.5 times until it gets to 7. So 20 x 3.5 is 70.
