On his first try , a pole-vaulter cleared 3.7 meters. on his second try the pole-vaulter cleared 45 centimeters more than his first try. what height, in meters did the pole-vaulter clear on his second try show your work

a.3.25
b.3.745
c.4.15
d.8.2

Do 3.7 / 10, since metric units are 10 in comparison, and you get 37 decimeters , which in turn, you divide again by 10 to get centimeters, so 370 centimeters.
Then add 45 to that to get 415 centimeters. Then multiply that by 100 to get back to meters, so 4.15 meters
