Question

Simplify $open parentheses 6 over 55 cross times fraction numerator negative 22 over denominator 9 end fraction close parentheses minus open parentheses 26 over 125 cross times fraction numerator negative 10 over denominator 39 end fraction close parentheses$

The correct answer is: rational numbers.

To simplify $open parentheses 6 over 55 cross times fraction numerator negative 22 over denominator 9 end fraction close parentheses minus open parentheses 26 over 125 cross times fraction numerator negative 10 over denominator 39 end fraction close parentheses$
On simplifications, we have $open parentheses fraction numerator negative 4 over denominator 15 end fraction close parentheses minus open parentheses fraction numerator negative 4 over denominator 75 end fraction close parentheses$
Determine the LCM of the denominators of rational numbers.
LCM of 15 and 75 = 75
On multiplying $fraction numerator negative 4 over denominator 15 end fraction$ with 5, we get $fraction numerator negative 4 cross times 5 over denominator 15 cross times 5 end fraction equals fraction numerator negative 20 over denominator 75 end fraction$
On multiplying $fraction numerator negative 4 over denominator 75 end fraction$ with 1, we get $fraction numerator negative 4 cross times 1 over denominator 75 cross times 1 end fraction equals fraction numerator negative 4 over denominator 75 end fraction$
On subtraction, we have $fraction numerator negative 20 over denominator 75 end fraction minus fraction numerator negative 4 over denominator 75 end fraction$
$not stretchy rightwards double arrow fraction numerator negative 16 over denominator 75 end fraction$

Perform multiplication and then subtract.
