48乘以0.72除以0.45乘以36要用简便运算不能超过7点,48乘以0.72除以0.45乘以36要用简便运算不能超过7点,48乘以0.72除以0.45乘以36要用简便运算不能超过7点,48*0.72

48乘以0.72除以0.45乘以36 要用简便运算不能超过7点,
48乘以0.72除以0.45乘以36 要用简便运算
不能超过7点,

48乘以0.72除以0.45乘以36 要用简便运算不能超过7点,
48*0.72/0.45*36
=48*0.8*0.9/0.9/0.5*36
=48*0.8/0.5*36
=3916.8

48 = 3*2*2*2*2
0.72 = 0.6 * 0.9 = 0.2 * 0.3 * 3 * 3
0.45 = 0.5 * 0.3 * 3
36 = 2 * 2 * 3 * 3
自己化简吧
