Lee and Maya are collecting leaves for an art project lee collects 25/100 of the total number leaves needed. Maya collects 4/10
MrRissso [65]

Answer:  The answer is \dfrac{13}{20}.


Step-by-step explanation:  Given that Lee and Maya are collecting leaves for an art project. Let'x' be the total number of leaves needed in the project.

Then, the number of leaves collected by Lee is given by

L_\ell=\dfrac{25}{100}x,

and the fraction of the leaves collected by Maya is given by

M_\ell=\dfrac{4}{10}x.

Therefore, the total number of leaves collected by Lee and Maya altogether is

L=L_\ell+M_\ell=\dfrac{25}{100}x+\dfrac{4}{10}x=\dfrac{25+40}{100}x=\dfrac{65}{100}x=\dfrac{13}{20}x.

Thus, the total fraction of the leaves collected by Lee and Maya is

\dfrac{13}{20}.
