Numeracy Foundation June 2022 Unit 2 Q5
5. Shaun is working on a project about the surface area of the Earth’s oceans.
He finds the following information about the proportion of the total surface area that is covered by each ocean.
| Ocean | Proportion |
|---|---|
| Pacific | 47% |
| Indian | 0·2 |
| Southern | 5% |
| Arctic | 0·03 |
| Atlantic | \(\dfrac{1}{4}\) |
Complete the table below to list the oceans in order of their surface area, starting with the largest.
The first line has been completed for you.
You must show how you decided on the order. [3]
| Ocean | |
|---|---|
| Largest | Pacific |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Showing (47%), 20%, (5%), 3% and 25% OR 0·47, (0·2), 0·05, (0·03) and 0·25 OR 47/100, 20/100, 5/100, 3/100 and 25/100 OR five correct calculations for a common amount | B2 | Look at the given table for some equivalent values B2 for all correct % OR all correct decimals OR all correct fractions with a common denominator OR correct work using a common amount OR a valid combination that allows full comparison Award B1 for any 2 correct conversions | ||||||||||||
| B1 | Allow any unambiguous indication (e.g. ‘converted values’). Strict FT of ‘their work’ if at least B1 gained. Correct answer (either oceans or proportions) with no other marks awarded, gains final B1. |
