7/15x3/8+1/15x7/16+1/15x3又1/2要脱式计算7/15x3/8+1/15x7/16+1/15x3又1/2要脱式计算7/15x3/8+1/15x7/16+1/15x3又1/2要脱式
7/15x3/8+1/15x7/16+1/15x3又1/2要脱式计算
7/15x3/8+1/15x7/16+1/15x3又1/2要脱式计算
7/15x3/8+1/15x7/16+1/15x3又1/2要脱式计算
7/15x3/8+1/15x7/16+1/15x3又1/2 =7/15x3/8+7/15x1/16+7/15x1/2 =7/15x(3/8+1/16+1/2) =7/15x15/16 =7/16
