Me ajude é só tres coisas !!

Answer 1

F) 224/225

$\frac{8}{9} \times\frac{48}{50} \times \frac{7}{6} =$

$\frac{2688 ^{ \div 2} }{2700 ^{ \div 2} } = \frac{1344 ^{ \div 2} }{1350 ^{ \div 2} } = \frac{672 ^{ \div 3} }{675 ^{ \div 3} } = \frac{224}{225}$

G) 5/4

$\frac{10}{12} \times \frac{48}{50} \times \frac{25}{16} =$

$\frac{12000}{9600} = \frac{120 ^{ \div 2} }{96 ^{ \div 2} } = \frac{60 ^{ \div 2} }{48 ^{ \div 2} } = \frac{30 ^{ \div 2} }{24 ^{ \div 2} } = \\ \frac{15 ^{ \div 3} }{12 ^{ \div 3} } = \frac{5}{4}$

H) 4/7

$\frac{2}{7} \times \frac{21}{14} \times \frac{8}{6} =$

$\frac{336 ^{ \div 2} }{588 ^{ \div 2} } = \frac{168 ^{ \div 2} }{294 ^{ \div 2} } = \frac{84 ^{ \div 3} }{147 ^{ \div 3} } = \frac{28 ^{ \div 7} }{49 ^{ \div 7} } = \frac{4}{7}$
