a. 16.4×6
b. 16.4−6
c. 16.4 + 6
d. 16.4÷6

Explanation:

Step1: Identify base value

Each group has 1 hundred (yellow), 3 tens (pink), 4 ones (blue) = $100 + 30 + 4 = 134$

Step2: Count total groups

There are 6 identical groups shown.

Step3: Match to expression

This represents 6 groups of 134, which is $134 \times 6$.
