Answer 1

The answer you want is going to be 164+3.28

Answer 2

Answer:

Step 3 is $=164 + 3.28$            

Step-by-step explanation:

Given : Yuuma applied the steps below to find the product of (–10.2)(–16.4).

To find : Which expression correctly fills in the blank in Step 3?

Solution :

The given expression is  $(-10.2)(-16.4)$

Step 1 : Write the expression,

$(-10.2)(-16.4) = (-16.4)(-10.2)$

Step 2: Distribute 10.2 into two parts 10+0.2

$=(-16.4)(-10) + (-16.4)(-0.2)$

Step 3: Simplify the multiplication,

$=164 + 3.28$

Step 4: Add the terms

$=167.28$

Therefore, Step 3 is $=164 + 3.28$
