The answer depends on the extent to which the number is being estimated.
The number divided by 100 then the answer to that times 15. eg 15 % of 20 is 20/100 =0.2 0.2 * 15 = 3 3 is 15 % of 20
In mathematics, an estimate is an approximation of a value based on available information. To estimate 15, you can round it to the nearest whole number, which is also 15. Another way to estimate 15 is to round it to the nearest multiple of 10, which would be 20. Both of these estimates provide a close approximation of the value of 15.
3 x 5 = 15
estimate of 24 mulitply by 15 = 300estimate of 24 = 2020 * 15 = 300
To estimate 15 divided by a number to the nearest tenth, first, identify a nearby divisor that makes the division simpler. For example, if dividing by 3, you know that 15 divided by 3 equals 5. If dividing by 4, you can estimate it as 15 divided by 4 is about 3.75, which rounds to 3.8 when considering the nearest tenth. This method involves rounding the result of the division to one decimal place.
I estimate 15 cm.
My estimate, based 15*17 is 25500.I can do 15*17 because it is 162-1.
You do not need to estimate. 5 - 15 = -10 and any estimation would require at least as much effort.
i would say they way to get the ballpark estimate is by taking the number. and see what is the estimate for that number and then you take that estimated number and then add to get your answer .
Estimate what to the nearest whole number?
The best estimate is 15 centimeters which is about 6 inches
Take any number, multiply by 15% and you have 15% of that number. 100x15% is 15. 15 is 15% of 100.
