WORKSHEET OF THE WEEK
This week, I wanted to share a Percentages Resource suitable for your Year 9 and Year 10 students. This Finding the Original Worksheet provides excellent practice on Reverse Percentages through examination-style questions, helping students find 100% from given values and original amounts after percentage changes. The worksheet also includes contextual worded problems mixing increases and decreases in GCSE Mathematics exam style, ensuring comprehensive preparation.
