I am doing a online course on rational expressions, specifically complex fractions without variables, does anyone know what happens in the explanation where I marked it in red. I don't know what they did to get 15/14

see below

Step-by-step explanation:

9/ 14

3/5

9/14 ÷ 3/5

Copy dot flip

9/14 * 5/3

Rewriting

9/3 * 5/14

3 * 5/14

Multiply 3*5

15/14

Change from an improper fraction to a mixed number

14/14 + 1/14

1 1/14

Step-by-step explanation:

9/14 × 5/3

The factors can be canceled if they are factors of both the numerator of the first fraction and the denominator of the second fraction. The factors get cancelled leaving the second fraction to a whole number.

3/14 × 5

(3 × 5)/14

15/14

(3x-8) or (3x+8)
