Question

calcule 4/5+6/5 ; 9/6+6/7 ; 8/6-6/6 ; 5/4-3/4 ; 5/8×8/3 ; 3/5×6/5×5 ; 8/5÷2/15 ; 2÷4/7 ; (5/8)2 ; √16/121​

Answer 1

Resposta:

4/5 + 6/5= 10/5= 2

9/6 + 6/7= 99/42

8/6 - 6/6= 2/6= 1/3

5/4 - 3/4= 2/4= 1/2

5/8 x 8/3= 40/24= 10/6= 5/3

3/5 x 6/5 x 5/1=

18/25 x 5/1= 90/25= 18/5

8/5 : 2/15= 8/5 x 15/2= 90/10= 9/1

2/1 : 4/7= 2/1 x 7/4= 14/4= 7/2

(5/8)²= 25/64

V16/121= 4/11

*o primeiro número em negrito é o resultado, os demais são reduzidos*

Espero que te ajude!!

Bons estudos!!
