Show your answer both before and after rounding. You need not show your work. Unrounded Rounded a) 1.11 + 1 + 2.019 = b) 6.7 times 0.1 times 9.888 times 2.00 = c) (5.2 + 5.31) times 7.3 = d) 42.83/pi^2 = e) (5952 times 0.107)/(14 times 295) =

Explanation / Answer

A.

146000000 = 1.46*10^8

0.000259 = 2.59*10^-4

0.88 = 8.8*10^-1

33003 = 3.3003*10^4

57 = 5.7*10^1

2.

A. unrounded = 4.129

Rounded = 4

B. Unrounded = 13.24992

Rounded = 10

C. Unrounded = 76.65

Rounded = 77
