Write four rational number having denominator 2

1/2; 3/2; 5/2;7/2

Step-by-step explanation:

Rational numbers are numbers that can be expressed as a fraction meaning the denominator would be non zero.

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

60: 45 =12: 9 =4: 3 so the answer is 4: 3
