Foundation November 2022 Paper 1 Q14
14 Work out \(\quad 0.37 \times 0.26\)
Give your answer as a decimal. [4 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| 222 or 740 with the 0 correct for the multiplication by 20 or 182 or 780 with the 0 correct for the multiplication by 30 | M1 | values may be seen separately or in rows ignore any decimal points |
| their \(222 +\) their 740 or their \(182 +\) their 780 | M1dep | ignore any decimal points |
| digits 962 | A1 | |
| 0.0962 | B1ft | ft their digits \(962 \div 10\,000\) |
| Alternative method 2 | ||
| At least three of 600, 140, 180 and 42 | M1 | may be seen in a grid ignore any decimal points |
| their \(600 +\) their \(140 +\) their \(180 +\) their 42 | M1dep | ignore any decimal points |
| digits 962 | A1 | |
| 0.0962 | B1ft | ft their digits \(962 \div 10\,000\) |
| Alternative method 3 | ||
 | M1 | at least three of the calculated values correct ignore any decimal points |
| Total calculated correctly for each diagonal for their table | M1dep | ignore any decimal points |
| digits 962 | A1 | |
| 0.0962 | B1ft | ft their digits \(962 \div 10\,000\) |
Additional guidance
| Ignore use of a decimal point anywhere until final mark | |
| Use the Alt that gives the best mark | |
| B1ft is not available for an answer involving digits 962, other than correct answer 0.0962 | |
| \(30 \times 20 + 7 \times 6 = 642\), answer 0.0642 | M0M0A0B1ft |
| Using fractions, digits 962 may be seen as part of a fraction for first A1 For unsimplified fractions, follow appropriate MS for M marks For simplified fractions, please follow the spirit of each MS for M marks | |
| Alt 1 If the 0 is missing or misaligned allow if units digit 2 in their answer for the first M1 If the 0 is missing allow 0 to be replaced by x for the first M1 | |
| Alt 2 If numbers are broken down further there can be only one error for the first M1 eg 20 10 7 and 20 6 needs five of 400, 120, 200, 60, 140, 42 | |
| Alt 3 Diagonals must slope consistently for M1 unless recovered Diagonals missing is M0 unless recovered |
