a) Let x be the portion of the original whole that one of the pieces represents. Then we know that:
3x = 1/8
Multiplying both sides by 4, we get:
12x = 1/2
Dividing both sides by 12, we get:
x = 1/24
Therefore, one of the pieces represents 1/24 of the original whole.
b) Since 3 out of 4 pieces amount to 1/8 of the original whole, we know that the remaining 1/4 must be equal to 7/8 of the original whole. Therefore, the small remaining part represents:
1/4 * 1/8 = 1/32
So the small remaining part represents 1/32 of the original whole.
