0.99×10.1-9.9×0.01简便运算？

Answer 1

0.99×10.1-9.9×0.01简便计算为：
=0.99×10.1-(9.9÷10)×(0.01×10)
=0.99×10.1-0.99×0.1
=0.99×(10.1-0.1)
=0.99×10
=9.9

Answer 2

因为0.99×10.1=9.9×1.01，所以原式等于9.9×1.01-9.9×0.01，运用乘法分配律逆运算有9.9×（1.01-0.01）=9.9

Answer 3

0.99×10.1-9.9×0.01
=0.99×10.1-0.99×0.1
=0.99*（10.1-0.1）
=0.99*10
=9.9

Answer 4

9.9-0.9 × 1.1-0.01 = 9.9-0.99-0.01 = 9.9 - (0.99 + 0.01) = 9.9-1 = 8.9 please accept the answer in time, thank you!

Answer 5

9.9-0.9 × 1.1-0.01 = 9.9-0.99-0.01 = 9.9 - (0.99 + 0.01) = 9.9-1 = 8.9 vänligen acceptera svaret i tid, tack!
