Mathematics

Fiona gets 25 sweets

Step-by-step explanation:

System of Equations

Paul, Fiona, and Pip have some sweets in the ratio 4:5:1. Let's call x,y, and z the number of sweets they have respectively.

The ratios can be written as three separate equations:

$\frac{x}{y}=\frac{4}{5}\qquad\qquad[1]$

$\frac{y}{z}=\frac{5}{1}\qquad\qquad[2]$

$\frac{x}{z}=\frac{4}{1}\qquad\qquad[3]$

Paul has 15 more sweets than Pip, then:

x = z + 15 [4]

Multiplying [3] by z:

x = 4z

Substituing in [4]

4z = z + 15

Subtracting z:

3z = 15

z = 15/3 = 5

Multiplying [2] by z:

y = 5z = 5*5 = 25
