Salary = 1/3
Remainder: 3/3 - 1/3 = 2/3
Savings= 3/8 (2/3)
= 6/24 or 1/4
LCD or 1/3 and 1/4: 12
Step 1: Re-write as similar fractions, then add:
4/12 + 3/12 = 7/12
Expenses + savings = 7/12
Step 2: Solve for the fractional part of the rest of her salary by subtracting 7/12 from the whole:
12/12 - 7/12 = 5/12
Rest of salary = 5/12
Step 3: Divide 5/12 equally among brother and sister:
(5/12) ÷ (2)
Rule in dividing fractions: Multiply the first term by the reciprocal of divisor.
(5/12) × (1/2) = 5/24
ANSWER: Each of Lilian's sibling receives 5/24 of her salary.
