Question

O valor da expressão : 4/7.49/64+(1-3/5):3/5+(1+1/3) é?
49/64 e raiz quadrada!

Answer 1

(4/7) × (√49/√64) + (1 - (3/5)) ÷ (3/5) + (1 + (1/3)) =

(4/7) × (7/8) + ((5/5) - (3/5)) ÷ (3/5) + ((3/3) + (1/3)) =

(28/56) + (2/5) ÷ (3/5) + (4/3) =

(1/2) + (4/3) + (2/5) × (5/3) =

(3/6) + (8/6) + (10/15) =

(11/6) + (10/15) =

(55/30) + (20/30) =

(75/30) =

(15/6) =

5/2 = 2,5
