You can put this solution on YOUR website! There are 240 total.
7/10 of those like math (what's wrong with the other 3/10??)
240 * .70 = 168 students who like math, leaving 3/10 who do not, or 240*.3 = 72
Half of the 168 students are girls, so 168 * .5 = 84
Answer:
240 Students total
168 students who like math
72 students who need to be introduced to the fun of math
84 girls like math; 84 boys like math
