Answer my question really quick name the equal parts of a whole

15. 1/4    16.1/8     17. 1/3    18./1/5

Step-by-step explanation:

how many times it is EQUALLY DIVIDED so if its split into fours like #15 then its 1/4 or 16 EQUAL PARTS 1/16

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
