I thought of number. my friend thought of a number too. a third of my number is half of his number. whose number is bigger?

Answer 1

(1/3)Y = (1/2)F

Y/3= F/2

2Y = 3F

Y = 3F/2 = 1.5F

Your number is 1.5 time's your friend's numbrer

Y >F if both numbers are positive, but if negative, then -3 < -2

-3 x 1/3 = -1

-2 x 1/2 = -1

Your number is bigger if positive, but smaller if negative

if you both thought of zero, then Your numbers are equal.

1/3 of 0 = 1/2 of 0
