快很急的

Answer 1

15.64减(5.64减2.7)
=15.64-5.64+2.7
=10+2.7
=12.7

4.32乘1.8加2.2乘4.32
=4.32×（1.8+2.2）
=4.32×4
=17.28

168.1÷（4.3乘2减0.4）
=168.1÷（8.6-0.4）=168.1÷8.2
=20.5

6.5乘8加3.5乘8减44
=（6.5+3.5）×8-44
=10×8-44
=80-44
=36

Answer 2

15.64减(5.64减2.7)
=15.64-5.64+2.7
=10+2.7
=12.7;
4.32乘1.8加2.2乘4.32
=4.32×(1.8+2.2)
=4.32×4
=17.28;
168.1除（4.3乘2减0.4）
=168.1÷(8.6-0.4)
=168.1÷8.2
=20.5;
6.5乘8加3.5乘8减44
=8×(5+3.5)-44
=8×8.5-44
=68-44
=24;
