c. 0.00934 m to 3 decimal places.​

(a) 123.517 to 2 decimal places = 123.52

(b) 14.328 km/hr to 1 decimal place = 14.3

(c) 0.00934 m to 3 decimal places = 0.009

Explanation:

a. 123.517 to 2 decimal places

⇒ to 2 decimal places = 123.52 ( round 7 to 1 since it is up to 5 and add it to 1 before it.)

b. 14.328 km/hr to one decimal place.

⇒ to 1 decimal place = 14.3 (round 8 to 1 since it is up to 5 and add it to 2 before it, the 2 becomes 3, round the 3 to 0 since it is less than 5)

c. 0.00934 m to 3 decimal places.​

⇒ to 3 decimal place = 0.009
