Answer:

<u>1/12</u>

Step-by-step explanation:

<u>Given</u>

  • 5/14 x 7/30

<u>Solving</u>

  • This can easily be solved by using cross-multiplication
  • If we are given a fraction a/b, it can be rewritten as a x 1/b
  • ⇒ 5 x 1/14 x 7 x 1/30
  • Now combine (7 and 1/14) and (5 and 1/30)
  • ⇒ 7 x 1/14 x 5 x 1/30
  • ⇒ 7/14 x 5/30
  • ⇒ 1/2 x 1/6
  • ⇒ <u>1/12</u>

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}
