Hello,
they decided to share 20 sweets, but Marcus took 8 sweets, so:
20-8=12
We have 12 sweets left.
x= number of sweets that Sally took y= number of sweets that Sammy took
We know that Sally took three times as many as Sammy, so: x=3y
There are 12 sweets:
x+y=12
Replacing x:
3y+y=12 4y=12 y=3
x=3*(3) x=9
Answer: Sally took 9 sweets and Sammy 3

Sammy received 3 sweets. This is calculated by setting variables for the number of sweets each person took and solving a simple equation. Verifying with the total leads to the same result.
