Question

Va rog repede,am nevoie doar de la ,,f,g,h,i,j,k,l’’

Answer 1

Răspuns:

f.2/5 * 3/7=6/35

g.1/9 * 3/5=3/45 (se simplifica prin 3) = 1/15

h. 4/5 * 11/8=44/40 (se simplifica prin 4) =11/10

i. 17/10 * 20/3=340/30 ( se simplifica prin 10)= 34/3

j. 1 1/3 *3/4=(1*3+1)/3 *3/4=4/3 * 3/4=1

k. 3 4/7 * 2/15= (2*7+4)/7 * 2/15=18/7 * 2/15=36/105 ( se  simplifica prin 3)=12/35

l.9/8* 1 3/5= 9/8 * (1*5+3)/5= 9/8 * 8/5=9/5
