**Ms. Sue**, Tuesday, September 13, 2011 at 7:38pm17 boys do not know how to swim. Therefore, 17 boys do swim.

100 - 34 = 66 girls

2/3 * 66 = 132/3 = 44

44 + 17 = ?

**Daniel**, Tuesday, September 13, 2011 at 7:42pmEasy. Ok

"Half the boys said....yes" which means half said no. 17 said no so that means 17 out of 34 boys know to swim. Now for the girls, we know there are 34 boys so that leaves 66 girls total. 66 multiplied by 2/3 is 44. (44 girls said yes.) 44+34= 78.

Therefore 78 seventh graders know how to swim

**?**, Monday, October 28, 2013 at 11:49pmHalf the boys said yes so half said yes. 17 boys said no so the other half said yes so 17 boys said yes. 17 + 17 = 34 boys total. Now 100 students take away 34 boys (students) which now leaves 66 students (girls) total.

now 2/3 of 66 is 44 because 22 times 3 = 66. so Now 44 girls said yes and 17 boys said yes so 44 + 17 = 61 seventh graders know how to swim.
