Write the fraction
2/7
as an equivalent fraction with the given denominator 28.

8/28

Step-by-step explanation:

2/7  = ?/28

Well we have both of the denominators, and all they did was multiply the denominator of "7" by 4 to get "28" as the other denominator, so now all we have to do is multiply the first numerator by 4 to get the equivalent fraction.

2*4/7*4 = ?/28

8/28 = ?/28

The given numerator will be 8.

2/7 is equivalent to 8/28

Hope this helped!

Have a day!

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.
