Question

(1/4-2/3)×(4/5-2/15)×(-3/5)

Answer 1

(1/4-2/3)×(4/5-2/15)×(-3/5)=(-5/12)×2/3×(-3/5)=1/6

Answer 2

1) $frac{1}{4}- frac{2}{3} = frac{3-8}{12} =- frac{5}{12}$

2) $frac{4}{5} - frac{2}{15} = frac{12-2}{15} = frac{10}{15} = frac{2}{3}$

3) $- frac{5}{12} * frac{2}{3} =- frac{5}{18} * (-frac{3}{5} )= frac{5}{18} * frac{3}{5} = frac{1}{6}$
