Sharing in a Given Ratio — GCSE Foundation · Ratio & proportion · Year 10.

Share an amount in a ratio by finding total parts, then the value of one part — the habit that trips pupils is dividing the whole amount by each ratio number separately.

Exam board alignment: Covers Foundation ratio skills across major GCSE specifications. Content is spec-neutral unless noted.
