add up the two weights. 150+120=170. now divide that by 10. 170 divided by 10 is 17. that is the answer(:
math........so confusing.
that is not possible. immagine someone weighing 17kg. it should be (150X6 + 120X4)divided by 2 which equals 138 kilos
The full answer is
- the 6 boys weigh a total of 6 x 150 = 900lb
- the 4 girls weigh a total of 4 x 120 = 480lb
- the total weight of all 10 kids is 900 + 480 = 1380lb
- the average weight of the 10 kids is 1380 / 10 = 138lb
