Landen spent L hours at the beach last weekend. Matéo spent 15% fewer hours at the beach than Landen did

fenix001 [56]

Answer: B, D, and E

0.85L

L-0.15L

L(1-0.15)

$L - \frac{15}{100}L$

$L - \frac{3}{20}L$

Step-by-step explanation:

L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or $\frac{15}{100}L$ . We subtract by L-0.15L or as $L - \frac{15}{100}L$ . This fraction can simplify to $L - \frac{3}{20}L$
