Miguel and Kat are reading the same book. Miguel reads 5 times as many

n200080 [17]

Answer:

$k=\dfrac{m}{5}$

Step-by-step explanation:

Let Kat reads k pages of the book.

Miguel reads 5 times as many pages of the book as Kat. So,

m = 5k ...(1)

Together they read 54 pages. i.e.

m+k = 54 ...(2)

From equation (1),

$k=\dfrac{m}5{}$

Hence, the equation that can be used to find how many pages Kat read is equal to $\dfrac{m}{5}$ .
