First add 8 and 9 to get 17. Then divide 340 by 17 to get 20. Then times 20 by 8 to find the number of girls or times 20 by 9 to get the number of boys. Number of girls: 160 Number of boys: 180
80 ÷ 9 = 8 remainder 8
It is: (9-4-2) times 8 = 24
8 x 9 = 72
6 goes in 12 times. 8 goes in 9 times. 9 goes in 8 times.
7x - 8 = 3x + 4 4x - 8 = 4 4x = 12 x = 3 Check it. 21 - 8 = 9 + 4 It checks.
