Question
- convertir 74 311 mm en pieds - pouces et au 16e\ près :
- nb pouces = 74 311 mm / 25,4 = 2 925,630\
- nb pieds = 2 925,630\ / 12 = 243,802
- nb pouces = 0,802 x 12 = 9,624\
- nb 16e\ = 0,624\ x 16 = 9,984/16\ -> 10/16\
réponse : 243-9 10/16\
- calculer la surface dun plancher qui fait 10-5\ de long par 12-3\ de larg
(réponse en m²) :
Step1: Convert length to decimal feet
Longueur : $10' + \frac{5}{12}' = 10 + 0.4167 = 10.4167'$
Step2: Convert width to decimal feet
Largeur : $12' + \frac{3}{12}' = 12 + 0.25 = 12.25'$
Step3: Calculate area in square feet
$A = 10.4167' \times 12.25' = 127.6042\ \text{ft}^2$
Step4: Convert to square meters
$1\ \text{ft}^2 = 0.092903\ \text{m}^2$, donc $A = 127.6042 \times 0.092903$
