Which one is 2/3 real rational irrational integer whole natural

1 answer:

3 0

$\frac{2}{3}$ is real and rational.

For it to be an integer, whole, or natural number, it would have to be a whole number. Since it can be written as a repeating decimal (.6666666...) it is not irrational either.

50% of a certain number is 39. What is the number?

Allushta [10]

Let that certain number be 'n'

50% (n) = 39

50% ⇒ 0.5

0.5 (n) = 39

Divide both sides by 0.5

0.5n = 39
/0.5 /0.5

n = 78.

So that certain number is actually 78! :)

CROSS CHECK:

50% of 78

0.5 × 78

= 39

Hope this helps! :)
