Question

Hi! i really need help on this question tell me if u think u know TYSSSM!!!

pila the woodpecker can drill a small hole in a tree trunk with 25 pecks, which is only 1/4% the average number of pecks that she can make each day. How many times per day can pila peck a tree?

Answer 1

well, we know that 25 pecks is 1/4% or namely 0.25%, less than 1%, and let's say the amount of pecks per day will be "x", which is 100% of that.

$\begin{array}{ccll} pecks&\%\\ \cline{1-2} 25 & \frac{1}{4}\\[1em] x& 100 \end{array} \implies \cfrac{25}{x}~~=~~\cfrac{ ~~ \frac{1}{4} ~~ }{100}\implies 2500=x\cfrac{1}{4} \\\\\\ 2500=\cfrac{x}{4}\implies 10000=x$
