Question

0.8×720×0.125 0.25×32×0.125 5.9×2.7＋3.57 42-3.8×5.9 12.5×4.8

Answer 1

0.8×720×0.125 =0.8* 1/8 *720=72

0.25×32×0.125 =0.25×4×8×0.125=1×1=1

5.9×2.7＋3.57 =(6-0.1)×2.7+3.57=16.2-0.27+3.57=19.5

42-3.8×5.9 =42-(4-0.2)×(6-0.1)=42-24+0.4+1.2-0.02=29.58

12.5×4.8 =12.5×8×0.6=60

43.2-1.8×3-4.6 =43.2-5.4-4.6=43.2-10=33.2
