Question 1151163
<br>
Given the ratio of 8:9 of girls to boys, one common way to start working the problem is to let the number of girls be 8x and the number of boys be 9x.<br>
Then, given that the total number of students is 340,<br>
{{{8x+9x = 340}}}
{{{17x = 340}}}
{{{x = 340/17 = 20}}}<br>
ANSWER: The number of boys is 9x = 9(20) = 180.<br>
