Question

Can you Convert 840 inches to cm. Use unit analysis to convert the rate.

Answer 1

we know that

1 in=2.54 cm

so

840 in

Applying proportion

1/2.54=840/x

x=(840*2.54)/1

x=2,133.6 cm

answer is

2,133.6 cm

Applying unit rate or unit analysis

we have

2.54 cm/in

Multiply by 840 in

2.54*(840)=2,133.6 cm40/
