Sandy finished 3/8 of her homework before supper and 4/8 after supper. What fraction of her homework did she finish in total?

Fresh day Coly, let's solve. Problem 1 a) What fraction of her homework did Sandy finish in total? Step 1: Add the fractions of homework finished before and after supper. (3)/(8) + (4)/(8) Step 2: Add the numerators since the denominators are the same. (3+4)/(8) = (7)/(8) Sandy finished (7)/(8) of her homework in total. b) What fraction of her homework will Sandy still have to do before school the next day? Step 1: The total homework is represented by 1 (or (8)/(8)). Subtract the fraction finished from the total. 1 - (7)/(8) Step 2: Convert 1 to a fraction with a denominator of 8. (8)/(8) - (7)/(8) = (8-7)/(8) = (1)/(8) Sandy will still have (1)/(8) of her homework to do. Problem 2 Hlengiwe has 2(5)/(8) bags of sweets and Craig has 3(7)/(8) bags of sweets. If they combine their sweets, how many bags of sweets will they have together? Step 1: Add the mixed numbers. Add the whole numbers and the fractions separately. 2(5)/(8) + 3(7)/(8) = (2+3) + ((5)/(8) + (7)/(8)) Step 2: Perform the addition. 5 + (5+7)/(8) = 5 + (12)/(8) Step 3: Simplify the improper fraction (12)/(8) to a mixed number. (12)/(8) = (8)/(8) + (4)/(8) = 1 + (4)/(8) = 1(4)/(8) Step 4: Add this back to the whole number and simplify the fraction part. 5 + 1(4)/(8) = 6(4)/(8) = 6(1)/(2) They will have 6(1)/(2) bags of sweets together. Problem 3 Lucas spent (5)/(12) of his salary on rent and another (6)/(12) of his salary on food. a) What fraction of his salary did he use for rent and food combined? Step 1: Add the fractions of salary spent on rent and food. (5)/(12) + (6)/(12) Step 2: Add the numerators since the denominators are the same. (5+6)/(12) = (11)/(12) Lucas used (11)/(12) of his salary for rent and food combined. b) What fraction of his salary was left over after these expenses? Step 1: The total salary is represented by 1 (or (12)/(12)). Subtract the fraction spent from the total. 1 - (11)/(12) Step 2: Convert 1 to a fraction with a denominator of 12. (12)/(12) - (11)/(12) = (12-11)/(12) = (1)/(12) Lucas had (1)/(12) of his salary left over. Got more? Send 'em 📸
