    To subtract fractions, we need to have a common denominator. In this case, the least common denominator (LCD) is 20. Let’s perform the subtraction:

    3/4 – 2/5

    To make the denominators the same, we can multiply the numerator and denominator of the first fraction (3/4) by 5, and the numerator and denominator of the second fraction (2/5) by 4:

    (3/4) * (5/5) – (2/5) * (4/4)
    = 15/20 – 8/20

    Now that the fractions have the same denominator, we can subtract the numerators:

    15/20 – 8/20 = (15 – 8)/20 = 7/20

    Therefore, the result of subtracting 2/5 from 3/4 is 7/20.
