Best ResponseYou've already chosen the best response.0\[\frac{2}{5} + \frac{7}{10} * \frac{3}{2} + \frac{4}{15}\] Find the lowest common denominator (LCD), which happens to be 30 \[\frac{12}{30} + \frac{21}{30} * \frac{45}{30} + \frac{8}{30}\]

Best ResponseYou've already chosen the best response.0The LCD is 60, so \[\frac{24}{60} + \frac{63}{60} + \frac{16}{60}\]

Best ResponseYou've already chosen the best response.0okay so that comes out to 55/60 right but the they say 55/60 = 11/12 I am not sure how they determined that???

Best ResponseYou've already chosen the best response.0You have to multiply \[\frac{5}{5} * \frac{11}{12}\] to get \[\frac{55}{60}\]. Remember that \[\frac{5}{5} = 1\] and multiplying any number by 1 will equal that number.
