脱式计算写过程(1)4/5+8×45%(2)3.3÷2又1/5×5% (3)8.8×(1+25%)(4)(13/5-0.8)÷(60%-6%)
脱式计算写过程
(1)4/5+8×45%
(2)3.3÷2又1/5×5%
(3)8.8×(1+25%)
(4)(13/5-0.8)÷(60%-6%)
脱式计算写过程(1)4/5+8×45%(2)3.3÷2又1/5×5% (3)8.8×(1+25%)(4)(13/5-0.8)÷(60%-6%)
1 4/5+8×45%=4/5+3.6=0.8+3.6=4.4
2 3.3+2又1/5×5%=3.3+2.2×0.05=3.3+0.11=3.41
3 8.8×(1+25%)=8.8×1.25=11
4 (13/5-0.8)÷(60%-6%)=(2.6-0.8)÷(0.6-0.06)=1.8÷0.54=10/3
1 4/5+8×45% 2 3.3+2又1/5×5% 3 8.8×(1+25%)
=4/5+3.6 =3.3+2.2×0.05 =8.8×1.25
=0.8+3.6 =3...
全部展开
1 4/5+8×45% 2 3.3+2又1/5×5% 3 8.8×(1+25%)
=4/5+3.6 =3.3+2.2×0.05 =8.8×1.25
=0.8+3.6 =3.3+0.11 =11
=4.4 =3.41
4 (13/5-0.8)÷(60%-6%)
=1.8÷0.54
=10/3
那么简单还用问的!
