The number of seashells that Jennifer gave to her younger brother was 40 seashells
The ratio shows a quantitative relation between two variables and explains the no of times in which a variable is contained in another.
The total number of seashells collected by Jennifer and Sarah = 120 seashells
If Jennifer gave 1/3 of seashells to her brother, Jennifer and Sarah had the same number of seashells.
To solve this,
- Let the number of Jennifer seashells = p
- Let the number of Sarah seashells = q
∴
The amount of seashells Jennifer gave to her younger brother is:
x = 1/3 × 120
x = 120/3
x = 40
Now, the remaining amount of seashells is 80. If Jennifer and Sarah divide the number of seashells equally among themselves.
Then, Jennifer will have the same number of seashells as Sarah
= 80/2
= 40 number seashells each for Jennifer and Sarah.
