问题描述:
-14×3/4-0.34×3/7+1/4×(-14)+4/7×-0.34(简便)
答
原式=—14(3/4+1/4)—0.34(3/7+4/7)=—14—0.34=—14.34
答
你好:
原式 =-14×3/4-0.34×3/7+1/4×(-14)+4/7×-0.34
= - 14×(3/4 + 1/4) - 0.34 × (3 / 7 + 4 / 7)
=- 14× 1 - 0.34 × 1
=- 14 - 0.34
=- 14.34
答
-14×3/4-0.34×3/7+1/4×(-14)+4/7×-0.34
=-14x(3/4+1/4)-0.34x(3/7+4/7)
=-14-0.34
=-14.34
答
-14×3/4-0.34×3/7+1/4×(-14)+4/7×-0.34
=-14×(3/4+1/4)-0.34×(3/7+4/7
=-14-0.34
=-14.34
