40 and 50
use compatible numbers to estimate each difference 84-36
45 X 40/6.1 = 295.081967213
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
To estimate 37x22, we can round each number to the nearest tens place, which would be 40 and 20. Then, we can multiply these rounded numbers together to get an estimate. 40 multiplied by 20 is 800. Therefore, the estimate of 37x22 is 800.
30 and 40
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 years if i estimate right
