When you divide two fractions, you do Keep, Change, Flip or KCF. So you keep the 3/5, you change the division sign to a multiplication sign, then flip the 3/15 to 15/3. So the new equation is 3/5x15/3. Then you simply the two sides so it becomes 1/1x3/1.....


Meaning the answer is 3.

Kay [80]

Step-by-step explanation:

Let there be x blue ribbons

\therefore \:  \frac{1}{5}  +  \frac{7}{15}  + x = 36 \\   \therefore \:  \frac{1 \times 3}{5 \times 3}  +  \frac{7}{15}  + x = 36 \\ \therefore \:  \frac{3}{15}  +  \frac{7}{15}  + x = 36 \\ \therefore \:  \frac{3 + 7}{15}   + x = 36 \\ \therefore \:  \frac{10}{15}   + x = 36 \\ \therefore \: x = 36 -  \frac{10}{15} \\ \therefore \: x =  \frac{36 \times 15 - 10}{15} \\ \therefore \: x =  \frac{540 - 10}{15} \\ \therefore \: x =  \frac{530}{15} \\ \therefore \: x =  35\frac{5}{15}  \\ \\  \therefore \: x =  35\frac{1}{3} \: are \: blue.  \\
