Question

find any ten rational number between (1/4 + 3/8) ÷ 2 and (3/8 + 1/2) ÷2​

Answer 1

→ To find a rational between a/b and c/d just calculate (a+c)/(b+d), and repeat this procedure as many times as needed. For example, between 1/8 and 1/2 you find 2/10 (or 1/5). Between 1/8 and 1/5 you find 2/13; between 1/5 and 1/2, 2/7, etc.
