Step-by-step explanation:
Rounding to nearest tenth:
i) if number in 100th place is 5,6,7,8 or 9, then add 1 to number in the tenth place and after adding remove all the digits right to it.
EG: 4.567 = 4.6
ii) if number in 100th place is 0,1,2,3 or 4, then write down number in the tenth place as it is and then remove all the digits right to it.
Eg: 4.523 = 4.5
a) 0.32 = 0.3 (b) 3.87 = 3.9 (c)0.709 = 0.7
d) 12.75 = 12.8 (d)12.745 = 12.8 e) 645.059 = 645.1
