    Answer: 3 / 20

    Step-by-step explanation:

    It is best to convert to decimals for such questions. It makes it faster.

    Nick mowed 3/5 of the lawn yesterday. In decimals this is:

    = 3/5

    = 0.60

    He then mowed another 1/4 this morning which is:

    = 1/4

    = 0.25

    As these decimals must add up to one, subtract the above from 1 to find the proportion left:

    = 1 – 0.6 – 0.25

    = 0.15

    Then convert back to fractions:

    = 0.15 = 15/100

    Lowest form would be gotten by dividing both the numerator and denominator by 5:

    = 3 / 20
