![]()
[tex] \sf \frac{8}{9} + \frac{3}{5} [/tex]
[tex] \sf = ( \frac{45 \: \div \: 9 \: \times \: 8}{45} ) + ( \frac{45 \: \div \: 5 \: \times \: 3}{45} )[/tex]
[tex] \sf = ( \frac{5 \: \times \: 8}{45} ) + ( \frac{9 \: \times \: 3}{45} )[/tex]
[tex] \sf = \frac{40}{45} + \frac{27}{45} [/tex]
[tex] \sf = \frac{40 \: + \: 27}{45} [/tex]
[tex] \sf = \frac{67}{45} [/tex]
[tex] \sf = \frac{1 \: \times \: 45 \: + \: 22}{45} [/tex]
[tex] = \sf \red{1 \frac{22}{45} }[/tex]
