Question

Simplify: 

i. \(\bar{3}\) .5472 - \(\bar{2}\) .8371 + 1.4581

ii. 1.2489 - \(\bar{1}\) .0891 + \(\bar{2}\) .8897.

Answer 1

i. \(\bar{3}\) .5472 - \(\bar{2}\) .8371 + 1.4581

=(\(\bar{3}\).5472 + 1.4581)- \(\bar{2}\) .8371

= \(\bar1\).0053 - \(\bar2\) .8371

= 0.1682

ii. 1.2489 - \(\bar1\).0891 + \(\bar2\) .8897

= (1.2489 + \(\bar2\) .8897) - \(\bar1\).0891

= 0.1386 - \(\bar1\).0891

= 1.0495
