Question

Which of the following expressions is shown in the below model?

• A. $\text{3}.01+0.104=3.114$
• B. $\text{3}.01+0.14=3.15$
• C. $\text{3}.1+0.4=3.5$
• D. $\text{.}31+0.14=0.45$

Answer 1

The correct option is A $\text{3}.01+0.104=3.114$

In the first model, there are 3 cubes and 1 rod.

This is equivalent to 3.01

In the second model, there are 1 flat and 4 units.

This is equivalent to 0.104

In the third model, there are 3 cubes, 1 flat, 1 rd and 4 units.

This is equivalent to 3.114.

Hence, the expression shown by the above model is 3.01+0.104=3.114
