40 and 50
45 X 40/6.1 = 295.081967213
use compatible numbers to estimate each difference 84-36
The closest estimate is, of course, the exact value.
To get 40% of something: 1. convert 40% to decimal a. Remove the % sign. b. Divide 40 by 100. thus, 40% = 0.40 2. Multiply 0.40 to something.
To the nearest ten, 40 cm
Estimate: 40 Actual: 37.92

41 percent percent of 40 = 0.164
The estimate would be 110. This is so because if you round 43, you get 40. I'd you round 68, you get 70. 40+70=110.
40 x 20 = 800
