2)6.6

3)0.83333

4)0.5233

5)1.2727

Answer 2

Terminal (0.043  and 6.6) and recurring. (0.833333333 , 0.52333333  and  1.272727)

Step-by-step explanation:

Two types of decimal expressions: Terminal and recurring.

Terminal or exact decimal number has a finite number of digits. Eg. 0.5, 0.125

Recurring or repeating decimal number does not stop at a given number of decimal places and may have repeating sets of digits after the decimal point. Eg. 1.33333, 3.14159265359

Terminal Decimals

(1) 43/1000 = 0.043

(2) 33/5 = 6.6

Recurring Decimals

(3) 5/6 = 0.833333333

(4) 157/300 = 0.52333333

(5) 14/11 = 1.272727
