Reduce the fraction 15 30 to halves.

Expert Solution & Answer
Check Mark
To determine

The fraction into its half.

Answer to Problem 1A

The fraction reduced to 12.

Explanation of Solution

Given:

The number is given as x=1530.

Concept used:

Divide numerator and denominator of the given fraction by GCF, that is, greatest common factor.

Calculation:

The factors of 15 are 1,3,5,15 and the factors of 30 are 1,2,3,5,6,10,15,30 respectively.

Therefore, the greatest common factor of 15 and 30 is 15.

Divide numerator and denominator of fraction by 15 as follows:

  x=15÷1530÷15x=12

Thus, the fraction reduced to 12.

Conclusion:

The fraction reduced to 12.

7. [10 marks] Let G = (V,E) be a 3-connected graph. We prove that for every x, y, z Є V, there is a cycle in G on which x, y, and z all lie. (a) First prove that there are two internally disjoint xy-paths Po and P₁. (b) If z is on either Po or P₁, then combining Po and P₁ produces a cycle on which x, y, and z all lie. So assume that z is not on Po and not on P₁. Now prove that there are three paths Qo, Q1, and Q2 such that: ⚫each Qi starts at z; • each Qi ends at a vertex w; that is on Po or on P₁, where wo, w₁, and w₂ are distinct; the paths Qo, Q1, Q2 are disjoint from each other (except at the start vertex 2) and are disjoint from the paths Po and P₁ (except at the end vertices wo, W1, and w₂). (c) Use paths Po, P₁, Qo, Q1, and Q2 to prove that there is a cycle on which x, y, and z all lie. (To do this, notice that two of the w; must be on the same Pj.)
