Rodrigo practiced playing the guitar 151_3 hours over the past 3 weeks. He practiced for 61_4 hours during the first week and 42_3 hours during the second week. How much time did Rodrigo spend practicing during the third week? Use the numbers and symbols to write an equation that represents the problem. Then solve the equation. Symbols may be used more than once or not at all.

Answer 1

47_6
because 61_4 plus 42_3 equal 103_7
now subtract 103_7 and 151_3
you get 47_6 which are the hours he practiced on the third week
