(a)
Paint needed for 1 table = 1 u
Paint needed for 1 gate = 4 u
Paint needed for 3 tables and 6 gates
= 3 x 1 u x 6 x 4 u
= 3 u + 24 u
= 27 u
37 of the paint = 27 u
17 of the paint = 27 u ÷ 3 = 9 u
Fraction of the remaining paint left
= 1 -
37=
47 47 of the paint = 4 x 9 u = 36 u
Remaining paint left = 36 u
Number of tables that Adam can paint with the remaining paint
= 36 u ÷ 1 u
= 36
(b)
Number of gates that Adam can paint with the remaining paint
= 36 u ÷ 4 u
= 9
Answer(s): (a) 36; (b) 9
