Using proportions, considering the amount she received from each person, it is found that Annie had 30 sweets originally.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that:
- Initially, she had n sweets.
- With the ones she got from Teddy, the amount became 1.5n.
- With the amount from Rosie, the amount became 1.4 x 1.5 x n.
The final amount was of 63, hence:
1.4 x 1.5 x n = 63
n = 63/(1.4 x 1.5)
n = 30.
Annie had 30 sweets originally.

No, its only a repeating decimal is the numbers repeating are the same each time
eg 0.987987987987... is
and 0.6666666... is
The given proportion of triangle ABC as AE/AD = EB/DC is; Not Accurate
<h3>Understanding Basic proportionality theorem(Thale's Theorem)</h3>
This theorem states that If a line is drawn parallel to one side of a triangle, then it cuts other two sides proportionally.
Thus, In ΔABC, DE || BC
By Thales theorem, we can say that;
AD/DB = AE/EC
Rearranging we can arrive at;
AE/AD = EC/DB
When we simplify further by adding 1 to both sides, we will get;
AD/AB = AE/AC
Thus, the given proportion is not accurate
