Pedro is building a spice rack with 4 shelves that are each 0.55 meter long. At the hardware store, Pedro finds he can only buy the shelving in whole meter lengths. Exactly how many meters of shelving does Pedro need? Since he can only buy whole number lengths, how many meters of shelving should he buy?
you multiply the numbers 4X0.55= 2.2 but since you need that 0.2 to complete the self you round up to 3
4 x 0.55 = 2.2 Round up to 3 Happy to Help!
