Answer: Meiyin saved 4/35 of her salary after giving portions to her father and mother.
Step-by-step explanation:
To find the fraction of her salary that Meiyin saved, we need to calculate the remaining fraction after she gave portions to her father and mother.
Let's start by representing Meiyin's salary as 1 whole unit.
Meiyin gave 2/7 of her salary to her father, which means she kept 5/7 for herself.
Out of the remaining 5/7, she gave 3/5 to her mother. To find the fraction that she saved, we need to subtract this portion from the remaining fraction.
So, the remaining fraction after giving to her mother is (5/7) - (3/5).
To subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 7 and 5 is 35.
Converting the fractions to have a denominator of 35:
(5/7) - (3/5) = (25/35) - (21/35) = 4/35.
Therefore, Meiyin saved 4/35 of her salary.
