Question

4 which model represents \\(\frac{3}{4}\\) of 28? (with images of models f, g, j and another unlabeled model)

Explanation:

Step1: Calculate \(\frac{3}{4}\) of \(28\)

To find \(\frac{3}{4}\) of \(28\), we use the formula \(a\times\frac{b}{c}\), where \(a = 28\), \(b=3\), and \(c = 4\). So, \(28\times\frac{3}{4}=\frac{28\times3}{4}\).
First, divide \(28\) by \(4\): \(28\div4 = 7\).
Then multiply the result by \(3\): \(7\times3=21\).

Step2: Analyze each option

• Option F:

Each group has \(6\) circles. There are \(4\) groups. \(3\) groups are shaded. The total number of shaded circles is \(3\times6 = 18
eq21\).

• Option G:

Not relevant calculation as per the value we found (\(21\)) doesn't match the pattern here.

• Option J:

Not relevant as the number of circles is too small.

Now, assume the un - labeled correct option (the one with \(21\) shaded circles among \(28\) total circles, grouped in a way that represents \(\frac{3}{4}\) of \(28\)) is the answer.

Answer:

The model which has \(21\) shaded circles (since \(\frac{3}{4}\times28 = 21\)) is the correct one.
