Paul leaves the library and walks 0.125 of a mile to his cousin’s house . he then walks 0.25 of a mile home. how far did paul walk?

1) for this type of exercise you must, add the amounts of miles to know the total  number of miles traveled by Paul

(1/8 + 1/4 )  = 1+2/8 = 3 /8  = 0,375 miles . the total number of miles traveled by Paul is 0,375 miles

$12. that is my answer.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
