Tina spends 25% of her day in school. she spends 1/3 of her day sleeping. she spends 1/8 of her time at soccer practice. how many free hours does tina have during the day?

This will involve adding fractions then subtracting. 25% is equivalent to 1/4. So you'll be adding 1/4 + 1/3 + 1/8. To add fractions you'll need to find a common denominator. 3, 4, & 8 area all factors of 24. So convert your original fractions to 1/4= 6/24, 1/3= 8/24, & 1/8= 3/24. Add your numerators 6+ 8+ 3= 17 which you'll put over the denominator of 24= 17/24. the original question asks how many free hours does she have. their are 24 hours in a day so now you'll subtract 17 from 24. 24-17= 7. She has 7 hours free in a day.

That little box would be 90 degrees. a triangle should be 180 degrees. 90 + 15= 105. 180-105=75. your answer would be 75 degrees but since you asked for the nearest tenth, it would be 80 degrees.
