Question

$\frac{3}{4} - \frac{5}{12 } \\ \frac{4}{5} \times \frac{15}{16} \\ 1 \times \frac{2}{3} \div \frac{15}{16} \\ \frac{(3) {}^{4} }{(5)} \div ( \frac{3}{5} )^{3}$

Answer 1

3/4 - 5/12 = ( 9 - 5 )/12 = 4/12 = 1/3

4/5 * 15/16 = 4 * 3/16 =  3/4 

1 * 2/3 : 15/16 = 2/3 * 16/15 = 32/45

(3)^4 / 5 : ( 3/5 )^3 = 3^4 / 5 : 3^3 / 5^3 = 3^4/5 * 5^3/3^3 = 3*5^3 = 2*25 = 75
