if not specified you do it to the lowest no. sig. fig. in the original equation. if you are only given 1 (not 1.000 i.e.) then do it to 1 sig. fig. in practice though, could get away with 3 sf because you will not be penalised for it
'25' is odd, all right, but not prime. (It can be divided by 1, 5, and 25) By the way, prime numbers must be odd numbers. All even numbers can be divided by 2, at least, and are therefore not prime.
use the divisibility rules. because these are all multiples of 10 right off the bat, you can divide all of them by 10 and use the numbers 5, 10 and 490 as your numbers instead. you can then use factor trees and prime factorization to help you. (I assumed that "divided evenly" you actually meant "multiplied evenly" as a smaller number cannot be divided evenly by a larger number)
It is one tenth. To explain: A fraction is a decimal converted to fraction form (and vice versa). When you want to convert a decimal to a fraction, count the number of places (numbers or digits) on the right side of the decimal. If it is 1 number, as in 0.1, then that is one tenth, or 1/10. To convert to fraction form, divide the number(s) to the right of the decimal by: * 10 if it's one number, as in 0.1 = 1 divided by 10 = 1/10 * 10 if it's one number, as in 0.3 = 3 divided by 10 = 3/10 It's done the same way no matter what the numbers are, it's how many numbers to the right of the decimal that you go by. For example: * 100 if it's two numbers, as in 0.01 = 1 divided by 100 = 1/100 * 100 if it's two numbers, as in 0.03 = 3 divided by 100 = 3/100
In 0.05, move the decimal point two spaces to the right. Do the same in 312.015 This problem has now become 31201.5 divided by 5.

8/3 divided by 4 = 2/3
-15+24a-1.6(2a)
And they are the ONLY consecutive prime numbers because if you have one prime number (i.e. 29), then there always is an even number right after the prime number (i.e. 30 comes right after 29), and consecutive means "right next to," right? And we all know that even numbers can always be divided in half, so 2 and 3 are the only consecutive prime numbers.
Tricky tricky, but 74/ 90 can be reduced/ divided by 2 right? Because they are both EVEN numbers, 74 divided by 2 is 37 while 90 divided by 2 would equal 45 right? So now your fraction become 37/45- 27 and 45 cant be divided by the same numbers, aside from 1, so this becomes your answer! 37 over 45! Learned this in my 7th grade class! Hope this helps! ~PEACE

The answer to 420 divided 16 would be 26.25. This is math problem.

The answer is simply,NO. Numbers never end and never count infinity as an actual number.
