Question

She wants to build a tower 35 in. tall using dominoes that are 1 and 2/5 in. tall. How many levels will her tower have?

Answer 1

25 levels

Explanation:

First, convert 1 2/5 to a decimal. Since 2/5=0.4, 1 2/5 is 1.4. Now, you can set up the following expression:

`\frac{35\text{in}}{1.4\text{in}}=25` levels.

Hope this helps!
