7/8:12.5%的最简比是多少?

对,都是875克。

x-7/8=12.5% x-7/8=1/8 x=7/8+1/8 x=1 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

28.8-(7.6+1/8÷12.5%) =28.8-(7.6+1) =28.8-8.6 =20.2

=3/7×1/8-2/7×1/8 =(3/7-2/7)X1/8 =1/7X1/8 =1/56

如图

=16.5×7.2×(12.5%-12.5%)×15/19 =0

c项错误,甲数是7的话,7*0.125=0.875 乙数是8比7多1.不是0.875

7.1*1/8+1.9*12.5%-0.125 =7.1*0.125+1.9*0.125-0.125 =(7.1+1.9-1)*0.125 =8*0.125 =1

2/7×1/8+12.5%×2/7+0.125×1/7 =2/7×1/8+1/8×2/7+1/8×1/7 =(2/7+2/7+1/7)×1/8 =5/7×1/8 =5/56

7/5除以12.5%加7/2乘8/1简便计算 =7/5➗0.125+7/2x8 =7/5➗(1/8)+7x4 =56/5+28 =11+1/5+28 =39又5分之1
