用简便计算99×48 解:采用分配律,原式=(100-1)x48 =100x48-48 =4800-48 =4752
一道简便计算,求解答 -
99×47+99 =99×48 =(100-1)×48 =4800-48 =4752
9.9×48 =(10-0.1)×48 =10×48-0.1×48 =480-4.8 =475.2
99x48+99x51+99简便计算 -
99x48+99x51+99 =(48+51+1)×99 =100×99 =9900
先把除号等换为乘号,然后利用乘法结合律,可得99x48÷48 =99 * 48 * 1/48 =99 * (48 *1/48 )=99 *1 =99
