Mr Vaidev wants to put all 38 boys and 88 girls into groups for an activity. There are more girls than boys in each group. Each group must have the same number of boys. Each group must also have the same number of girls.
- What is the greatest number of groups Mr Vaidev can form with these conditions?
- How many pupils are in each group?
(a)
Factors of 38 = 1, 2, 19, 38
Factors of 88 = 1, 2, 4, 8, 11, 22, 44, 88
Greatest number of groups Mr Vaidev can form
= Highest common factor of 38 and 88
= 2
(b)
Number of boys in each group = 38 ÷ 2 = 19
Number of girls in each group = 88 ÷ 2 = 44
Number of pupils in each group
= 19 + 44
= 63
Answer(s): (a) 2; (b) 63
