My question is: Toby's father gave him $343 for passing the test. Toby decided to share it with his two brothers, so he gave each of them 1/7 of $343. How many dollars are left for Toby? Your thoughts:
Toby gave each of his brothers 1 / 7 * $343 = $49. Toby gave his 2 brothers a total of 2 * $49 = $98. So, Toby now has $343 $98 = $245. The final answer: 245.
