35 boys 21 girls. mei ling surveys 16 girls. barry surveys 28 and 12 and halmi surveys 14 and 14. who would have the most appropiate information.

Halmi had the most appropriate information because when you add both the girls and the boys up it is 56 after that you have to add 14+14=28.

28/56= exactly %50 of the entire group.

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.
