A. 用简便方法计算47x72十47x27十47
47x72十47x27十47
=47x(72十27+1)
=47x100
=4700
B. 47ⅹ74x27的简便方法
解:47×74×27等于( 93906 )
∵已知需求出47×74×27等于多少
∴47 × 74 × 27
= [47 × (70 + 4)] × 27
= (47 × 70 + 47 × 4)× 27
= (3290 + 188)× 27
= 3478 × 27
= 3478 × (30 - 3)
= 3478 × 30 - 3478 × 3
= 104340 - 10434
= 93906
答:47×74×27等于93906
C. 47×402的简便方法
简便计算如下
47×402
=47×(400+2)
=47×400+47×2
=18800+94
=18894
D. 47x72-47x22用乘法分配率怎么算
47x72-47x22
=47x(72-22)
=47x50
=2350
以上就是简便计算方法。
E. 47x98的简便运算
47×98简便运算是把乘法运算化为减法运算
98=100-2
47×98
=47×(100-2)
=4700-47×2
=4700-98
=4600+(100-98)
=4600+2
=4602
