Question

how to find 10 rationa number between -2/5 and 1/2

Answer 1

Ans.

In numbers -2/5 both numerator and denominator multiply by 2, then

-2×2/5×2 = -4/10

and number 1/2 both numerator and denominator multiply by 5, then

1×5/2×5 = 5/10

Hence, the rational numbers between -4/10 and 5/10 are :-

-4/10, -3/10, -2/10, -1/10, 0, 1 /10, 2/10, 3/10, 4/10,5/10.

Answer 2

to find 10 rational number between -2/5 and 1/2
firstly multiply -2/5 by 2/2 and 1/2 by 5/5
hence,-2/5 ×2/2 = -4/10 and 1/2 × 5/5=5/10
now we have -4/5 and 5/10 so to find 10 rational number between them multiply by 10 on both sides -4/10×10/10 and 5/10× 10/10
so, -40/100 and 50/100
hence rational number are -41/100,-42/100,-43/100,-44/100,-45/100,-46/100,-47/100,-48/100,-49/100 -50/100
