Answer 1

Respuesta:

a. 2/6 + 1/2 = 5/6 ,

b.3/7 + 2/3 = 14 + 9 /21 = 23/21 ; 1 $\frac{2}{21}$

c. 5/4 - 6/7 = 35 - 24/28 = 11 /28

d. 3 $\frac{2}{3}$ - 1/4 = 11/3 - 1/4 = 44 - 3 /12 = 41/12; 3$\frac{5}{12}$

e. 1   $\frac{5}{6}$- 9/8 = 11/6 - 9/8 = 66 - 27/24 = 39/24 ; 1 $\frac{15}{24}$

f. 2  $\frac{2}{13}$ + 5/5 = 28/13 + 5/5 = 240 + 65 / 65 = 305/65 = 61/13 = 4 $\frac{1}{15}$
