Use the following set definitions to specify each set in roster notation.
except where noted, express elements as cartesian products as strings. a = {a} b = {b, c} c = {a, b, d} (a) a × (b ∪ c) keyboard_arrow_up solution {aa, ab, ac, ad} (b) a × (b ∩ c) keyboard_arrow_up solution {ab} (c) (a × b) ∪ (a × c) (d) (a × b) ∩ (a × c) (e) (c × b) ∩ (b × c) (f) p(a × b) (g) p(a) × p(b). use ordered pair notation for elements of the cartesian product. with just f and g.
(c)
(a × b) ∪ (a × c)
(d)
(a × b) ∩ (a × c)
(e)
(c × b) ∩ (b × c)
(f)
p(a × b)
(g)
p(a) × p(b). use ordered pair notation for elements of the cartesian product.

Equivalent fractions and ratios mean that when simplified, they are the same one fraction or ratio. see examples below.

Step-by-step explanation:

For example, the fraction 1/2 is the same as 2/4 or 15/30 because when you simplify them, they are still 1/2. Therefore they are equivalent.

For example, the ratio 1:2 is the same as 5:10 or 10:20 since when broken down they all come down to 1:2. Hence they are equivalent.

Hope this answers your question.
