Answer 2

Step-by-step explanation:

A.

1.we know that 1 yard = 91.44 cm

5 yards =5×91.44 cm=457.2 cm

5 yards = 457.2 cm

2.we know that 2.54 cm = 1 inch

=>1 cm= 1/2.54 inch

20.32 cm = 20.32×1/2.54

=>20.32/2.54

=>2032/254

=>8 inches

20.32 cm= 8 inches

3.we know that 1 feet =30.48 cm

1 cm =1/30.48 feet

91.44 cm=91.44×1/30.38

=>91.44/30.38

=>9144/3038

=>3 feet

3 feet =91.44 cm

4.we know that 2.54 cm = 1 inch

=>3 inch = 3×2.54 cm

=>7.62 cm

3 inch =7.62 cm

B.

1.we know that 1cm = 10mm

=>5cm=5×10 mm

=>50 mm

5 cm=50 mm

2.we know that 1 dm =100 mm

=>2 dm=2×100=200mm

2 dm= 200 mm

3.we know that 1 foot =12 inches

=>3 feet=3×12 =36 inches

3 feet = 36 inches

4.we know that 1 yard =36 inches

=>1 inch =1/36 yards

=>72 inches =72/36=2 yards

2 yards = 72 inches
