A) 0,5 + 0,4 b) 0,01 + 0,3 c) 0,9 - 0,3. 2. Calculate the following and then round off your answers to two decimal places: a) 32,452 + 9,543 + 0,5409 b) 98,4311 - 88,31 + 54,1034

$$0.5 + 0.4 = 0.9$$

$A_1 = 0.9$

$$0.1 + 0.3 = 0.4$$

$B_1 = 0.4$

$$0.9 - 0.3 = 0.6$$

$C_1 = 0.6$

$$4.52 + 9.543 + 0.5609$$

Add first two terms:

$$4.52 + 9.543 = 14.063$$

Add the third term:

$$14.063 + 0.5609 = 14.6239$$

Round 14.6239 to two decimal places (third decimal is $3 < 5$, so no rounding up):

14.62

$$43.1 - 88.93 + 54.1034$$

First, $43.1 + 54.1034 = 97.2034$

$$97.2034 - 88.93 = 8.2734$$

Round 8.2734 to two decimal places (third decimal is $3 < 5$, so no rounding up):

8.27
