Max says 5/10 + 43/100 = 48/100. Maria says 5/10 + 43/100 = 93/100.
Who is correct? ______________________
Shade the problem on the decimal strip using two different colors.
5/10=50/100 so 50/100 + 43/100 = 93/100
Maria is correct.
*Check shading on strips.

DJ makes beaded bracelets and necklaces. He has 2 storage boxes for his beads. The first box has 12 sections, with 8 large beads in each section. The second box has 15 sections with 25 small beads in each section. How many more small beads than large beads does he have?
Write an equation to represent this problem. Use a letter to stand for the unknown.
Solve this problem - show your work!
Equation (15 x 25) - (12 x 8) = B (beads)
375 - 96 = 279 more small beads
