1、24.6-3.98+5.4-6.02
解析：此题利用加法交换结合律，凑整再计算。步骤如下：
24.6-3.98+5.4-6.02
=（24.6+5.4）-（3.98+6.02）
=30-10
=20
2、27×17/26
解析：此题先用加法分配律，把27转换成（26＋1），再利用乘法结合律，使得运算简便。
27×17/26
＝（26＋1）×17/26
＝26×17/26＋1×17/26
＝17＋17/26
＝17又17/26
3、528-99
解析：利用凑整法和减法结合律计算，先利用凑整法把99变换为（100-1），再运用a-b-c=a-(b+c)来简便计算，步骤如下：
528-99
=528-（100-1）
=528-100+1
=428+1
=429
4、1.2×2.5+0.8×2.5
解析：运用提取公因数的方法，公式：ac+ab=a(b+c)，提取公因数2.5，1.2和0.8相加正好凑整数，使得运算简便。
1.2×2.5+0.8×2.5
=（1.2+0.8）×2.5
=2×2.5
=5
5、2.96×40
