鸡和兔子在同一个笼子里
1.假设都是兔子。88×2 = 176 244-176 = 68 68÷(4-2)= 34只兔子88-34 = 54只鸡方程:解法:设兔子为X,则鸡为88-X. 4x+(88-x) 2 = 2446x = 68x。兔子34只,88-34 = 50只鸡!!2.假设所有玩家都玩跳棋。6×26=156棋手156-120 = 36棋手36 ÷ (6-2) = 9棋手26-9 = 17跳棋。3.假设所有的硬币都是镍币。5×40=200点=2元2-1.7 = 0.3元=30点30 ÷ (5-2) = 10 2点40-10 = 30 5点4。假设天气晴朗。16×17=172乘以222-172 = 50乘以50÷(16-11)= 10雨天65438。!!!!!!!!!!!!!!
