Răspuns:

Explicație pas cu pas:

c. 33/16 - 5/16 : 5/8 - 3/4 * 3/4 = 33/16 - 5/16*8/5 - 9/16 = 24/16 - 1/2 = (24-8)/16 = 16/16 = 1

d. 1/6+1/2+1/3 = (1+3+2)/6 = 6/6 = 1

e. 1/3+2/3 = 3/3 = 1

f. 99/100*10/11 + 17/40*4/17 = 9/10+1/10 = 10/10=1

g. 5/18 + 14/9*3/7 + 1/2*1/9 = 5/18+2/3 + 1/18 = 6/18+2/3= 1/3+2/3 = 3/3 = 1

h. x/(x+1) + x/(x²+x) = (x²+x)/(x²+x) = 1
