Question

Simplify
9.8 - [5.6 - {7.8 - (2.4 - (5.5 – 2))}] +0.9​

Answer 1

Answer:

13.8

Step-by-step explanation:

9.8-[5.6-{7.8-(2.4 -(5.5-2 ))}]+0.9

=9.8-[5.6-{7.6-(2.4-3.5)+0.9

=9.8-[5.6-{7.6-(-1.1)}+0.9

=9.8-[5.6-{7.6+1.1}+0.9

=9.8-[5.6-8.7]+0.9

=9.8-(-3.1)+0.9

=9.8+3.1+0.9

=12.9+0.9

=13.8
