<h3>Answer: 1/42</h3>
Explanation:
Draw 6 identical rectangles side by side as shown in figure 1 in the diagram below. Shade one of the rectangles to represent 1/6 of the cake left over.
Now draw in horizontal lines (see figure 2) to split the leftover amount into 7 equal portions. Notice that we have a 7 by 6 grid of tiny rectangles. There are 7*6 = 42 tiny rectangles in total.
Each person will therefore get 1/42 of the original cake when splitting up this last leftover slice.

as product of primes, we obtain:
If we express the monomial
as product of primes we obtain:
The least common multiple of these two binomials is the product of the highest powers of the common factors.
The LCM is
Therefore the correct answer is D.
A segment bisector is a segment, ray, line, or plane that intersects a given segment at its midpoint.
