Question

find a numerator that makes the statement true. there may be more than one correct answer. the fraction you make must be greater than 0 and less than 1. the numerator must be a whole number. \\(\frac{5}{10} < \frac{\square}{8}\\)

Explanation:

Step1: Simplify the left fraction

Simplify \(\frac{5}{10}\) to \(\frac{1}{2}\), which is \(0.5\).

Step2: Let the numerator be \(x\)

We have the inequality \(\frac{5}{10}<\frac{x}{8}\), and also \(\frac{x}{8}<1\) (since the fraction is less than 1). From \(\frac{x}{8}<1\), we get \(x < 8\). From \(\frac{5}{10}<\frac{x}{8}\), cross - multiply: \(5\times8<10x\), so \(40 < 10x\), then \(x>4\). Since \(x\) is a whole number and \(4 < x < 8\), possible values of \(x\) are 5, 6, 7. Let's check \(x = 5\): \(\frac{5}{10}=0.5\) and \(\frac{5}{8}=0.625\), and \(0.5<0.625\) and \(0.625 < 1\).

Answer:

5 (or 6 or 7, here we take 5 as an example)
