Question

which expression can be represented by the model? 16×10 16×0.1 1×0.6 1×6

Explanation:

Step1: Analyze the model

Each square represents 1, divided into 10 equal parts. The second square has 6 blue parts, which is $\frac{6}{10}=0.6$ of 1.

Step2: Match to the expression

The model shows 1 whole square plus 0.6 of a square, which corresponds to $1 \times 0.6$ (representing the shaded 0.6 portion of the unit square, and the full square is 1, but the expression that matches the fractional part representation is $1 \times 0.6$).

Answer:

$1 \times 0.6$
