1- a is a ratio that compares a number to 100. 2. a is an equation that shows that two ratios are equivalent. 3. in a one ratio compares a part to a whole. 4. a number that can be written as a fraction is a h i . p 5. the is the least common multiple of the denominators of two or more fractions.

the answer is d on edge

step-by-step explanation:

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
