Step-by-step explanation:
all easily found in the internet.
let's start with
1 inch = 2.54 cm
1 ft = 12 in = 2.54×12 = 30.48 cm
1 yd = 3 ft = 3×30.48 = 91.44 cm
1 meter = 100 cm
this should be enough to answer the problems :
a.)
25 ft = 25 × 30.48 cm = 762 cm = 762/100 m = 7.62 m
b.)
67 m = 6700 cm = 6700/2.54 in = 2,637.795276... in
c.)
8.5 yd = 8.5 × 91.44 cm = 777.24 cm
d.)
90 cm = 90/2.54 in = 35.43307087... in
