Answer:
The: Symbol, fraction symbol, and to.
Explanation:
Using the : symbol — 2:5.
As a common fraction — 25. The first number in the ratio is the numerator; the second number is the denominator. Ratios written as a common fraction are read as a ratio, not as a fraction. Say “2 to 5,” not “two-fifths.”
Using the word “to” — 2 to 5.
