7. The lengths of three ropes are in the ratio 3 : 4 : 5. The total length of the three ropes is 180 cm.
What is the length of the shortest rope?

 

Answer:   cm

 

 

📖 REMINDER: Add the ratio parts to find the total parts. Divide the total length by total parts to find the value of one part. Multiply by the smallest ratio part to get the shortest length.
