384除以3除以4的脱式计算

请看图

450-384除以24×15 =450-16x15 =450-240 =210

脱式计算方法先乘除后加减 384+18*25*4 =384+450*4 =384+1800 =2184

384÷22+23x371 =192/11+20X371+3X371 =17+5/11+7420+1113 =5/11+7420+1130 =5/11+8550 =8550又11分之5

(1)72÷9×156,=8×156,=1248;(2)462÷(2×3),=462÷6,=77;(3)4001-384÷6,=4001-64,=3937.

(1)(384+336)÷15×13,=720÷15×13,=48×13,=624;(2)(11+30.6)÷16+16.5,=41.6÷16+16.5,=2.6+16.5,=19.1;(3)2- 5 4 × 8 15 - 1 3 ,=2- 2 3 - 1 3 ,=2-( 2 3 + 1 3 ),=2-1,=2;(4)[1-( 1 6 + 1 4 )]÷ 7 10 ,=[1- 5 12 ]...

450÷75+384÷16用脱式计算 450÷75+384÷16 =6+24 =30.

535-384+927 =151+927 =1078

=(316+384)+218 =600+218 =818
