Yea Any integer can be written as a fraction! Just put that integer as the numerator of a fraction with a denominator
Step-by-step explanation:
integers are whole numbers.
3/5 is a rational number because it represents a ratio of two integers (and denominator ≠0).
Step-by-step explanation:
f(2) = 2^2 +2
= 4+2

c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7
Convert mixed fraction into a simple fraction
6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7
c/7 = 43/7
proportionality:
a/b = c/d where ad = bc
a = c
b = 7
c = 43
d = 7
ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43
20/ X= 100
⇒ X= 20/100 (inverse operation)
⇒ X= 1/5
Final answer: X= 1/5
