Answer:

$\dfrac{156}{44}\times \dfrac{7}{4}=\dfrac{273}{44}\quad \left(\mathrm{Decimal:\quad }\:6.20455\dots \right)$

Step-by-step explanation:

$\dfrac{156}{44}\times \dfrac{7}{4}$

$\gray{\mathrm{Cross-cancel\:common\:factor:}\:4}$

$=\dfrac{39}{44}\times \dfrac{7}{1}$

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

$=\dfrac{39\times \:7}{44\times \:1}$

$\gray{\mathrm{Multiply\:the\:numbers:}\:39\times \:7=273}$

$=\dfrac{273}{44\times \:1}$

$\gray{\mathrm{Multiply\:the\:numbers:}\:44\times \:1=44}$

$=\dfrac{273}{44}$
