Finley has 72 sweets - OCR - GCSE Maths - Question 15 - 2023 - Paper 1

Next, to find the sweets given to Umi, calculate ( \frac{1}{6} ) of 72:

$$\frac{1}{6} \text{ of } 72 = \frac{72}{6} = 12$$

Finley gives 12 sweets to Umi.

Now, add the sweets given to Alex and Umi to find the total given away:

$$Total \text{ given } = 18 + 12 = 30$$

Finally, subtract the total given away from the initial amount to find how many sweets are left:

$$Sweets \text{ left } = 72 - 30 = 42$$

To show this as a fraction of the total, calculate:

$$\frac{Sweets \text{ left}}{Total} = \frac{42}{72} = \frac{7}{12}$$

Thus, Finley has ( \frac{7}{12} ) of the sweets left.
