Sep 27, 2016

$3$ $3$

Explanation:

"Doubled" means two of them..
You can do this by adding or by multiplying..

$1 \frac{1}{2} + 1 \frac{1}{2} = 1 + 1 + (\frac{1}{2} + \frac{1}{2})$ $1 1/2 +1 1/2 = 1+1+(1/2+1/2)$

$= 1 + 1 + 1 = 3$ $=1+1+1 = 3$

OR using improper fractions..#3/2+3/2 = 6/2 =3#

OR $1 1/2 xx 2 = 3/cancel2 xxcancel2/1 = 3$
