Question

Resuelve las siguientes operaciones 4/5×(2/3+7/5 b (9/10×1/3)(4/5÷1/2) c (8/7÷3/9)+(9/4-1/2) d(7/10×45/3)+(13/5÷14/4) me ayudan plis

Answer 1

A) 4/5x(2/3+7/5) = 4/5x(10/15+21/15) = 4/5x(31/15)= 124/75
B) (9/10x1/3)(4/5:1/2) = (9/30)(8/5)= (3/10)(8/5)=24/50 = 12/25
C) (8/7:3/9)+(9/4-1/2)=(72/21)+(9/4-2/4)=(24/7)+(7/4)= 145/28
D) (7/10x45/3)+(13/5:14/4)=(315/30)+(52/70)= 63/6 + 26/35 = 787/70
