Afactory worker can make 14 products in 45 minutes what is the worker's unti rate

This depends on what you are trying to convert it to.

If you are trying to find how many products he makes per hour, you can set up the equation to be 14/45 is equal to x/60 and try and solve for x

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
