Anna took brownies to a club meeting. She gave half of her brownies to Selena. Selena gave third of her brownies to Randall. Ran dall gave a fourth of his brownies to Trina. If Trina has three brownies, how many brownies did Anna have in the beginning?
2 answers:
3x4=12, 3x13=36, 36x2=72, so she started off with 72 brownies.
If Trina has 3 and Randall gave her a fourth multiply 3 by 4: Randall had 12. If Randall had 12 and Selena gave him a third multiply 12 by 3: Selena had 36. If Selena had 36 and Anna gave her half multiply 36 by 2: Anna had 72. Anna had 72 brownies at the beginning :)
