Answer 2

Answer:

$\green{\dfrac{7}{2}\times \dfrac{10}{49}\times \dfrac{5}{2}=\dfrac{25}{14}\quad \left(\mathrm{Decimal:\quad }\:1.78571\dots \right)}$

Step-by-step explanation:

$\dfrac{7}{2}\times \dfrac{10}{49}\times \dfrac{5}{2}$

$\gray{\mathrm{Multiply\:fractions}:\quad \dfrac{a}{b}\times \dfrac{c}{d}=\dfrac{a\:\times \:c}{b\:\times \:d}}$

$=\dfrac{7\times \:10\times \:5}{2\times \:49\times \:2}$

$\gray{\mathrm{Multiply\:the\:numbers:}\:7\times \:10\times \:5=350}$

$=\dfrac{350}{2\times \:49\times \:2}$

$\gray{\mathrm{Multiply\:the\:numbers:}\:2\times \:49\times \:2=196}$

$=\dfrac{350}{196}$

$\gray{\mathrm{Cancel\:the\:common\:factor:}\:14}$

$=\dfrac{25}{14}$
