What is between 3/8 and 7/16
Anit [1.1K]

Answer:

13/32 is one of the numbers between 3/8 and 7/16

Step-by-step explanation:

The set of rational numbers is very dense.

For any given two rational numbers, we can find infinitely many rational numbers between them.

Similarly, there are many rational numbers between 3/8 and 7/16.

One of them is the number in the middle.

To find it add and divide the result by 2.

\frac{ \frac{3}{8}  +  \frac{7}{16} }{2}

\frac{ \frac{6}{16}  +  \frac{7}{16} }{2}

\frac{ \frac{13}{16} }{2}

\frac{13}{32}
