Question

find four rational number between 1 and -2​

Answer 1

Answer:-9/5, -8/5,........3/5, 4/5

Step-by-step explanation:=(-2/1) and (1/1)

we have to find 4 rational no.'s. So

• =(-2/1)x5 and (1/1)x5
• =(-10/5) and (5/5)
• =19/5, -8/5, -7/5,-6/5,.........2/5, 3/5, 4/5,

Answer 2

The rational number between a and b is (a + b)/2

Hence rational number between 1 and -2 is (1-2)/2 = -1/2 = -0.5

Rational number between 1 and -1/2 is [1+(-1/2)]/2 = 1/4 = 0.25

Rational number between 1 and 1/4 is [1+(1/4)]/2 = 5/8 = 0.625

Rational number between -2 and 1 is = 0

Therefore four rational numbers between 1 and -2 are -1/2 , 1/4 , 5/8 , and 0 .
