Question

Evaluate using properties of arithmetic operations. 12∙121∙13÷(26∙11)∙7÷11

Answer 1

0.1978

Explanation:

According to the rule of BODMAS (or FEDMAS), let us do the bracket first.

26·11 = 286

Now, do the multiplication from the left.

12·121·3 = 4356

286·7 = 2002

Now, do the division from the left.

`((4356)/(2002) )/(11)`

`=(4356)/(2002(11))`

`=(396)/(2002)`

= 0.1978
