Hannah says that 2.11 is a rational number. gus says that 2.11 is a repeating decimal.

Yes, she is correct.

Step-by-step explanation:

A real number that can be expressed as ,

Where,

p and q are integers,

Such that, q ≠ 0,

is called a rational number.

A terminating decimal is always a rational number,

Thus, 2.11 is a rational number,

Verification :

2.11 =

Where,    

Both 211 and 100 are integers,

Such that 100 ≠ 0.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
