you can make it into an improper fraction if you want but there is no need for this problem
steps
1) 10 3/4- 5 1/4
10-5=5
3/4-1/4=2/4 or 1/2

(it is better simplified)
1m is approximately 3 feet whereas 1m is approximately 3280 feet. Therefore, the best estimate for the heiht of a desk would be 1 m
46.94 ≈ 47
7.09 ≈ 7
10/40 = (10*1)/(10*4) = (10/10)*(1/4) = 1/4
