Answer:
11/12
Step-by-step explanation:
2 3/4 = 2·(4/4) + 3/4 = (8/4) +(3/4) = (8+3)/4 = 11/4
Then your problem becomes ...
(11/4) / 3 = (11/4) · (1/3) = (11·1)/(4·3) = 11/12
___
The numerator and denominator have no common factors, so this is lowest terms.
Set up an equation and then solve for x. Luke has x amount and Tom has twice as many so that is 2x.
x + 2x =39
3x=39
Divide by 3
x= 13 so ...
Luke has 13 marbles and Tom has 2 times x so Tom has 2x13=26 marbles. 13+26=39
