Answer

Therefore, the least common denominator for the fractions is $140 r^{5}$ .

Steps

Step 1 ：The least common denominator (LCD) of two fractions is the least common multiple (LCM) of their denominators. In this case, the denominators are $35 r^{5}$ and $20 r^{3}$ .

Step 2 ：To find the LCM of these two expressions, we need to find the LCM of their numerical coefficients (35 and 20) and the highest power of r that appears in either expression ( $r^{5}$ ).

Step 3 ：The LCM of 35 and 20 is 140, and the highest power of r is $r^{5}$ .

Step 4 ：Therefore, the least common denominator for the fractions is $140 r^{5}$ .
