问题描述:
8分之5比4分之1(求比值)0.6比2分之1(求比值)0.5t比200g(化简比)16分之5比0.25(化简比)0.36比6比值
0.8*3分之2+5分之1/0.75
答
(5/8):(1/4)=2.5; 0.6:(1/2)=1.2; 1t=1000kg,所以(0.5t):(200g)=(500000g):(200g)=5000:2; 0.25=1/4 所以(5/16):(0.25)=(5/16):(1/4)=5:4
答
2.5 1.2 5000比2 5比4 0.06
答
5/8:1/4
=20/8
=5/2
0.6:1/2
=3/10:1/2
=6/10
=3/5
0.5t:200g
0.5t=500g
原式=500g:200g
=5:2
5/16:0.25
=5/16:1/4
=5/4
0.36:6
=1:100
最后一题,得:6/5+4/15
=22/15
