after typing 1/4 of a term paper on Friday, Richard completed 2/3 of the remainder on Saturday. If he wanted to finish the paper that weekend, what part was left to be typed on Sunday a=1/4 b=2/3 c=1/3 d=1/2

1/4 (A)

Step-by-step explanation:

Let the term paper = x

Richard typed 1/4 of a term paper on Friday = 1/4 * x = x/4

Remainder = x - x/4 = (4x-x) / 4

= 3x/4

Richard completed 2/3 of the remainder on Saturday = 2/3 of remainder

= 2/3 * 3x/4

= 6x/12 = x/2

Remainder to be completed on Sunday = 3x/4 - x/2

= (3x-2x) / 4 = x/4

Since he wanted to finish the paper that weekend, the part that was left to be typed on Sunday = x/4

= x * 1/4 (A)
