Question

9/11 - 4/15 please solve it​

Answer 1

Respuesta: The result id 91/165

Explicación paso a paso: You have to do the least common multiple of 11 and 15, which is, {11 = 11 × 1 and 15 = 3 × 5} then multiply 11 × 3 × 5 = 165. Once these steps are done, you raise the two fractions with 165 as the denominator in each of the two, when you already have this, you divide 165 ÷ 11 = 15 and multiply, 15 × 9 = 135. In the next fraction, the same, 165 ÷ 15 = 11 and multiply 11 × 4 = 44. You already have the fractions, 135/165 and 44/165, now you subtract the numerator of both fractions leaving the same denominator, 135-44 = 91/165
