Luis used a calculator to find a decimal and a percent equal to 1/4. how might luis done this

I divide the numerator by the denominator

He divided the numerator and denominator :

1÷4=0.25=25%

hope this helped

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
