(a)
Fraction of the people that are adults =
56 Fraction of the adults that are women =
15 Fraction of the people that are women
=
56 x
15 =
16 (b)
Total number of chicken wings
= (1 u x 4) + (5 u x 3)
= 4 u + 15 u
= 19 u
19 u = 95
1 u = 95 ÷ 19 = 5
Number of adults
= 4 u + 1 u
= 5 u
= 5 x 5
= 25
Answer(s): (a)
16; (b) 25
