I think you mean 510 / [tex]\frac{1}{10}[/tex]
So 510 divided by one tenth
Dividing a fraction is the same as multiplying the inverse
An inverse of a fraction is 1 divided by the number, or basically "flipped"
ex.
Original fraction [tex]\frac{1}{9}[/tex] Inverse: [tex]\frac{9}{1}[/tex]
Original: [tex]\frac{36}{1}[/tex] Inverse: [tex]\frac{1}{36}[/tex]
The inverse of [tex]\frac{1}{10}[/tex] is [tex]\frac{10}{1}[/tex], or simply just 10
So we need to multiply 510 by the inverse of [tex]\frac{1}{10}[/tex], or 10
510 * 10 = 5,100
