Answer 2

Step-by-step explanation:

i) take the denominator of denominator to numerator and denominator of numerator to denominator

$\frac{3 \times 2}{10 \times 1}$

$\frac{6}{10} = \frac{3}{5}$

ii)

$\frac{7 \times 5}{10 \times 2 } \\ = \frac{35}{20} \\ = \frac{7}{4}$

iii) first change the mixed fraction into improper fraction,

$\frac{14 \div 3}{28 \div 9} \\ = \frac{14 \times 9}{28 \times 3} \\ = \frac{126}{84} = \frac{3}{2}$

iv) make mixed fraction to improper fraction

$\frac{11 \div 4}{4 \div 5} \\ = \frac{11 \times 5}{4 \times 4} \\ = \frac{55}{16}$

mark as brainliest!!

hope this helped
