1.递等式计算,能简算的要简算:
(14.4-14.4÷120)÷0.2 | 0.25×(40+4) | 6.8×3.7+3.7×3.2 |
307×10.1 | 9.2÷0.4-9.2×0.4 | 8.3×2.7-2.7+2.7×2.7 |
20.直接写得数:
0 164542 164550 164556 164560 164566 164568 164572 164578 164580 164586 164592 164596 164598 164602 164608 164610 164616 164620 164622 164626 164628 164632 164634 164636 164637 164638 164640 164641 164642 164644 164646 164650 164652 164656 164658 164662 164668 164670 164676 164680 164682 164686 164692 164698 164700 164706 164710 164712 164718 164722 164728 164736 199269
0.44+0.6= | 4.8÷0.48= | 2.4×0.5= | 0.2+0.8×0.2= |
1-0.25= | 0.2+0.8×0.2= | 0.2÷0.5= | 0.6×0.5÷0.6×5= |
