Answer 1

$297. \ a) frac{8 times 3}{3 times 40} = 5 \ b) frac{10 times 11 times9}{12 times 10 times 11} = frac{3}{4} \ v) frac{6 times 12}{20 times 9} = frac{2}{5} \ q) frac{3 times 4 times 5}{24 times 15} = frac{25}{20} = frac{5}{4} = 1 frac{1}{4}$

$298. \a) frac{5 {}^{2} }{5 {}^{3} } = 5 \b ) frac{3 {}^{3} }{3 {}^{5} } = frac{1}{9} \ v) frac{2 times 3 {}^{3} }{2 {}^{2} times 3 times 5 } = frac{9}{10} \ q) frac{2 {}^{3} times 3 {}^{2} times 7}{2 {}^{2} times 5 {}^{3} } = frac{126}{125}$
