Question

What is the value of the expression shown by the following models?

• A. $\text{4}.136$
• B. $\text{4}.106$
• C. $\text{5}.136$
• D. $\text{5}.136$

Answer 1

The correct option is A $\text{4}.136$

First model has one flat and 6 units.

This is equivalent to 0.106.

Second model has 4 cubes and 3 rods.

This is equivalent to 4.03.

Sum of the decimals = 0.106 + 4.03 = 4.136

Hence, sum of the decimals shown by the model is 4.136.
