first you would have to estimate the division problem once you do that just move your decimal 2 spaces to the right for example if you have four eighths you would round four to five and eight to ten and then you divide
A percent is a ratio of a number to 100.
Two choices: -- Multiply (the number) x (the percent using the percent % key). -- Multiply (the number) x (the percent), then divide the answer by 100. Either way, the claculator displays that many percent of that number.
To find 12.5 percent of a number, multiply the number by 0.125.
15
If 15 percent of a number N is 0.3 what is 45 percent of N
When you wish to compare is to another number.
To find 78 percent of a number, multiply that number by 0.78. In this instance, 0.78 x 2890 = 2254.2.
Estimate: 70 percent of 50 (I lowered the percent, so I rounded the number up. My way of estimating) which is 35. Actual: 32 3/25
41 percent percent of 40 = 0.164
12.22
52% of 38 = 0.52 * 38 = 19.76 which when estimated to the nearest whole number = 20.
Estimate: 40 Actual: 37.92
there is no need for an estimate - exact answer is 212.80
It is 0.8
23 percent of 81 is 18.63.
100%
Since 50% of 16 is 8 we can estimate that 52 percent of 16 would be slightly higher than 8, or 8.1-8.4.
