Mgbe ahụ chọpụta ngụkọta nke sentimita nke naịlọn e ji mee ihe maka olu akwa: 10 sentimita / olu akwa * 3 olu akwa = 30 sentimita. Mgbe ahụ, gbakwunye naịlọn dị mkpa maka olu nkịta na nke nwamba iji chọta ngụkọta a chọrọ: sentimita iri isii na abụọ + sentimita iri atọ = sentimita iri abụọ na abụọ. <eng> First find the total number of inches of nylon used for the dog collars: 18 inches / dog collar * 9 dog collars = 162 inches. Then find the total number of inches of nylon used for the cat collars: 10 inches / cat collar * 3 cat collars = 30 inches. Then add the nylon needed for the cat and dog collars to find the total amount needed: 162 inches + 30 inches = 192 inches.
