Keith spent 1/5 of this money on a story book. He gave $26.80 to his brother and had 1/2 of his money left. How much money did h e have left?
2 answers:
1/5 = 2/10 1/2 = 5/10 2/10 of his money on a story book. Storybook is the variable x $26.80 to his brother (5/10 of his money left) 5/10-2/10 = 3/10 $26.80x3/10= 8.04 He had $8.04 left.
Not really sure of this one but i think it's like this- 2/10 (money for story) + 3/10 (26.80 dollars to brother)= 1/2 of his money 3/10x=26.80 268=3x ; x= 89.33333.... 89.33 X 5/10= answer money left= (roughly) 44.67
