the answer is 4, not 3 1/3
first, convert 1 1/3 to improper fraction
you can do this by multiplying the denominator by the whole number, 1 x 3 = 3
then, you add the numerator; 3 + 1 = 4
you then keep the denominator. 4 is now your numerator- so it's 4/3
next just multiply 4/3 x 3
3 & 3 are like terms which means they cancel out each other
which equals 4
in conclusion,
you're left with 4!!
