0.125乘以3/4+8分之1×8点二五+12/百点五脱式计算
0.125×3/4+1/8×8.25+12.5%
=1/8×(3/4+8.25+1)
=1/8×10
=1.25
13×3/8加13×12/百点二五+13乘以二分之一
13×3/8+13×12.5%++13×1/2
=13×(3/8+12.5%+1/2)
=13×1
=13
2×1/4加一点8×0点二五+25/百
2×1/4加一点8×0点二五+25/百
=1/2+0.45+0.25
=0.5+0.7
=1.2。
1/4×36加63×0点二五 25/百
1/4×36加63×0点二五+ 25/百
=0.25×36+63×0.25+0.25

x-8分之1 3/20=1点二五
x-8分之1 +3/20=1点二五
x =5/4 + 1/8 - 3/20
x=49/40
简算37×25/百+42×4分之一减39×0点二五
37×25%+42×4分之一-39×0.25
=37x0.25+42x0.25-39x0.25
=(37+42-39)x0.25
=40x0.25
=10
1/4×4又3/7)+0点二五×4又4/7+4分之一
简便计算
1/4×4又3/7+0.25×4又4/7+1/4
=1/4×(4又3/7+×4又4/7+1)
=1/4×10
=2.5
0.25乘以8+4分之1乘以95+25%
解:原式=0.25x8+0.25x95+0.25
=0.25(8+95+1)
=26
18乘以百分之25+4分之1乘以60+42乘以0.25
实际就是(18+60+42)*0.25=120/4=45
