Question

b) 42307 cg = ____ kg
e) 5.21 g = ____ mg
h) 3085 mg = ____ g
b) 5 yd = ____ ft
e) 120 in = ____ ft
h) 7 yds = ____ in
) 3636 in = ____ yd
) 73 ft = __ yds __ ft

Explanation:

Step1: Convert centigrams to kilograms

1 kg = 100000 cg, so $42307\ cg=\frac{42307}{100000}\ kg = 0.42307\ kg$

Step2: Convert grams to milligrams

1 g = 1000 mg, so $5.21\ g=5.21\times1000\ mg = 5210\ mg$

Step3: Convert milligrams to grams

1 g = 1000 mg, so $3085\ mg=\frac{3085}{1000}\ g = 3.085\ g$

Step4: Convert yards to feet

1 yd = 3 ft, so $5\ yd = 5\times3\ ft=15\ ft$

Step5: Convert inches to feet

1 ft = 12 in, so $120\ in=\frac{120}{12}\ ft = 10\ ft$

Step6: Convert yards to inches

1 yd = 36 in, so $7\ yds=7\times36\ in = 252\ in$

Step7: Convert inches to yards

1 yd = 36 in, so $3636\ in=\frac{3636}{36}\ yd = 101\ yd$

Step8: Convert feet to yards and remaining feet

1 yd = 3 ft, $73\div3 = 24$ yd with a remainder of 1 ft, so $73\ ft = 24\ yds\ 1\ ft$

Answer:

b) 0.42307 kg
e) 5210 mg
h) 3.085 g
b) 15 ft
e) 10 ft
h) 252 in
) 101 yd
) 24 yds 1 ft
