    7/10 hours

    Step-by-step explanation:

    her first assignment took 1/2 hour

    her second assignment took 1/5 hour

    so in total she took 1/2 + 1/5

    we need to find a common denominator

    the lcm (2,5) = 10

    so multiply 1/2 by 5/5 to obtain 5/10

    multiply 1/5 by 2/2 to obtain 2/10

    5/10 + 2/10 = 7/10
