Lower primary school mathematics question LPQ102
48 friends and relatives visited Sarin’s family during Hari Raya Puasa. 1/8 of them were adults. There were 8 fewer boys than girls.
- How many adults were there?
- What fractions of the people are boys and what fractions are girls?
1/8 of the visitors were adults and 7/8 of the visitors were children,
8 units = 48
1 unit = 48 ÷ 8 = 6
The number of adults = 6
The number of children = 7 × 6 = 42
Among the children, 8 fewer boys than girls,
Per the model,
2 units = 42 – 8 = 34
1 unit = 17
The number of boys = 17
The number of girls = 17 + 8 = 25
The total number old visitors were 48,
The fraction of people were boys = 17/48
The fraction of people were girls = 25/48
