Brandon's plant grew 4 and 3/4 cm last month. Jake's plant grew 2 and 2/5 cm last month. Care's plant grew 5 and 1/2 cm last month. What is the combined height that all of their plants grew last month?

Respuesta :

4and3/4 is 15/4
2 and 2/5 is 12/5
5 and 1/2 is 11/2
15/4+12/5+11/2=5.5+4.75+2.4=12.65
