Answer:

$\dfrac{1}{12}$

Step-by-step explanation:

Rewrite the denominators as products of factors, then cancel the common factors.

$\begin{aligned}\dfrac{5}{14} \times \dfrac{7}{30} & =\dfrac{5}{2 \cdot 7} \times \dfrac{7}{6 \cdot5}\\\\ & = \dfrac{5 \cdot 7}{2 \cdot 7 \cdot 6 \cdot 5}\\\\ & = \dfrac{1}{2 \cdot 6}\\\\ & = \dfrac{1}{12}{\end{aligned}$

<h3>What is subtraction?</h3>

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

A scientist wants to know if there is a meaningful difference between two groups of gels that grow bacteria. He randomly selects five gels from each group, and counts the number of bacteria spots on each gel:

Group A: 9, 12, 13, 14, 17

The difference between the numbers will be given below.

3, 1, 1, 3

Group B: 6, 5, 8, 13, 8

1.When all the three cut outs of the angles A, B, C placed adjacent to each other at a point, then it forms a line forming a straight angle, i.e. 180°.

Flence, it is proved that the sum of the three angles of a triangle is 180°.

Therefore, ∠A + ∠B + ∠C =180
