Answer:

Step-by-step explanation:

Given : Sydney applied the steps below to find the product of (3.1)(-1.6).

To find : Which expression correctly fills in the blank in Step 2?

Solution :

Step 1 : Commutative property applied, ab=ba

(3.1)(-1.6)=(-1.6)(3.1)

Step 2 - Apply distributive property a(b+c)=ab+ac by re-write 3.1=3+0.1

(3.1)(-1.6)=(-1.6)(3+0.1)

(3.1)(-1.6)=(-1.6)(3)+(-1.6)(0.1)

Step 3 - Solve the multiple,

(3.1)(-1.6)=(-4.8)+(-0.16)

Step 4 - Add the terms,

(3.1)(-1.6)=-4.96

Therefore, In Step 2 the expression is Option 4 is correct.
