Mai's younger brother tells her that 10/7 is equal to square root of 2. Mai knows this can't be right,

because 10/7 is rational and square root of 2 is irrational. Write an explanation that Mai could use

to convince her brother that 10/7 cannot be the square root of 2.

10/7 is a simple fraction, and √2 cannot be written as a simple fraction. So, they are not the same.

Step-by-step explanation:

10/7 is a number that has a numerator and a denominator.

Suppose √2 = 10/7, then √2 can also be written as a number that has a numerator and a denominator.

Since this is not the case, 10/7 cannot be the same as √2.
