2^2 + 12/9 ÷ 2/7

= 2^2 + 12/9 ÷ 2/7

= 4 + 12/9 ÷ 2/7

= 4 + 4 2/3

= 4 + 14/3

= 12/3 + 14/3

= 26/3

= 8 2/3

2^2 + 12/9 ÷ 2/7 = 26/3 = 8 2/3

$mathfrak{{2}^{2} + frac{12}{9} div frac{2}{7} } =$

$mathfrak{= (2 times 2) + frac{12}{9} times frac{7}{2}}$

$mathfrak{ = (2 + 2) + frac{12 × 7}{9 times 2} }$

$mathfrak{= 4 + frac{84}{18} }$

$mathfrak{ = frac{4}{1} + frac{84}{18} }$

$mathfrak{ = frac{4 times 18}{1 times 18} + frac{84}{18} }$

$mathfrak{= frac{72}{18} + frac{84}{18} }$

$mathfrak{= frac{72 + 84}{18} }$

$mathfrak{ = frac{156}{18} }$

$mathfrak{ =8 frac{12}{18} }$

$bf = 8 frac{2}{3}$
