Сложите дроби, предварительно сократив их: Образец 6/15+5/25=3*2/5*3+5*1/5*5=2/5+1/5=3/5. б). 10/16+3/24; в). 30/45+8/36; г). 60/120+75/150; д). 24/360+16/480.

Б). 10/16+3/24 = (2*5) / (2*8) + 3 / (3*8) = 5/8+1/8=6/8 = (2*3) / (2*4) = 3/4

в). 30/45+8/36 = (15*2) / (15*3) + (4*2) / (4*9) = 2/3+2/9 = (2*3) / (3*3) + 2/9=

=6/9+2/9=8/9

г). 60/120+75/150=60 / (60*2) + 75 / (75*2) = 1/2+1/2=2/2=1

д). 24/360+16/480=24 / (24*15) + 16 / (16*30) = 1/15+1/30=

= (2*1) / (2*15) + 1/30=2/30+1/30=3/30=3 / (3*10) = 1/10
