How is the numeral 35.012 written in words and why

1 answer:

5 0

Thirty-five and twelve thousandths because...
35 is just thirty-five
The decimal point in words is 'and'
And the 012 goes to the thousandths place...
One place after the decimal place is tenths
Two places is hundredths
And three places is thousandths
Does that help?

An army contingent of 104 members is to march behind an army band of 96 members in a parade.

You can dispose a number $x$ of elements in a matrix-like formation with $n\times m$ shape if and only if $n$ and $m$ both divide $x$ , and also $nm=x$ .

So, we need to find the greatest common divisor between $104$ and $96$ , so that we can use that divisor as the number of columns, and then.

To do so, we need to find the prime factorization of the two numbers:

$104 = 2^3\times 13$

$96 = 2^5 \times 3$

So, the two numbers share only one prime in their factorization, namely $2$ , but we can't take "too many" of them: $104$ has "three two's" inside, while $96$ has "five two's" inside. So, we can take at most "three two's" to make sure that it is a common divisor. As for the other primes, we can't include $3$ nor $13$ , because it's not a shared prime.
