270 divided by 6 = 45

you can do regular division or long division

ANSWER

45

EXPLANATION

Method 1

First we perform the division:

[tex] \frac{2430}{9} [/tex]

We then express both the numerator and the denominator as product of primes.

[tex] \frac{2 \times {3}^{5} \times 5 }{ {3}^{2} }[/tex]

Cancel the common factors to get:

[tex]2 \times {3}^{5 - 2} \times5[/tex]

The quotient is

[tex]2 \times {3}^{3} \times5[/tex]

We again divide the quotient by 6 to get,

[tex] \frac{2 \times {3}^{3} \times5}{6} = \frac{2 \times {3}^{3} \times5}{2 \times 3} = {3}^{2} \times 5 = 45[/tex]

Method 2:

[tex] \frac{2430}{9} \div 6 = \frac{2430}{9\times 6} = \frac{2 \times {3}^{5} \times5}{ {3}^{3} \times 2} = 45[/tex]
