How could we determine the Mixed number and decimal equivalence?
How could we determine the fraction and decimal form?
Model 2
Model 1
Model 2 = 1 2 %
½ of a square shaded
100 total
Model 1 = 130% = 130
100
A percent greater than 100% equals a number greater than 1
So ½% = 0.5%Look %
Teacher Notes: Discuss with students model 1 represents a mixed number where the whole number and fraction are written together with the understanding they are to be added to together. .
