Take the first few digits, if the next one is f or more, increase the last digit used by 1. Replace all subsequent digits with 0.
When working with very large numbers or very small numbers and they would use a system of numeracy known as scientific notation.
Obviously "large numbers"
the answer is yes because you can estimate any numbers
Estimate 43/81 by using compatible numbers
They are capable of reproducing in large numbers because they have spores
When dealing with very large numbers or very small numbers where a relatively small number of significant figures are required.
The numbers of large canivores in the desert are low as the biome cannot support large numbers of them. There is not enough food to feed large numbers of carnivores so they are rearely seen.
estimate
In the same way as you estimate them for whole numbers.
To estimate quotients, round the dividend and the divisor to compatible numbers.
Large number1+large number2
The best way to estimate a quotient using compatible numbers is to first understand how compatible numbers work. They are numbers that are close in value to the actual numbers and are easily added, subtracted or divided.
