(a)
Fraction of the people that are adults =
34 Fraction of the adults that are men =
13 Fraction of the people that are men
=
34 x
13 =
14 (b)
Total number of nuggets
= (1 u x 4) + (3 u x 3)
= 4 u + 9 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Number of adults
= 2 u + 1 u
= 3 u
= 3 x 2
= 6
Answer(s): (a)
14; (b) 6
