Complete the statement below to explain how this model shows that 1/2 ÷ 2/3 = 3/4.
Sindrei [870]

Given a model in which some boxes are given.

Here, 1/2 is represented by 3 boxes and 2/3 is represented by 4 boxes. Thus, the model represents that 3/4 of 2/3 bar is equal to 1/2.

So, the mathematical representation of the model is:

\frac{1}{2}=\frac{3}{4}\times\frac{2}{3}

If we divide both the sides by 2/3, we get:

\begin{gathered} \frac{1}{2}\div\frac{2}{3}=\frac{3}{4}\times\frac{2}{3}\div\frac{2}{3} \\ \frac{1}{2}\div\frac{2}{3}=\frac{3}{4} \end{gathered}

Is there a smallest decimal that is greater than the number 2? Explain your answer.
olga nikolaevna [1]

Answer:

Technically, yes. It's called epsilon, which is defined as an infinitely small number. So

 2 + epsilon is the smallest number greater than 2. But for practical purposes no there isn't.

00

Step-by-step explanation:Not without limits. You can always move the .1 one place further from the interring. For example,  

2.1>2.01

and  

2.01>2.001

So, unless there are a limited number of decimal spaces, you can continually add an infinite amount of zeros behind the decimal point, followed by a one.

If you use two or three decimal spaces as a standard in your class, then the smallest decimal greater than 2 would be 2.01 or 2.001, respectively.
