Question

Simplificati fractiile astfel incat sa devina ireductibile:4 pe 10..............28 pe 84...........333 pe 444...........25 pe 3250 ...........2x5x7 pe 3x5x11............2 la puterea a 3a  pe 2 la puterea a 5-a5 la puterea  a 4a x 7 la 3 x 11 la 4..............5 la 6 x 7x 11 la 3..............3a+6b pe 5a+10b .................9a+3pe 12a+4

Answer 1

4/10=2/5
28/84=1/3
333/444=3/4
25/3250=1/130
2x5x7/3x5x11= 14/33
2^3/2^5=8/32=1/4
5^4x7^3x11^4/5^6x7x11^3 = 7^2x11/5^2x1x1
(3a+6b)/(5a+10b)=3(a+2b)/5(a+2b)=3/5
(9a+3)/(12a+4)=3(3a+1)/4(3a+1)=3/4
