Question

calcula el valor de las siguientes expresiones sabiendo que a=3/5, b =8/3, c=5,d=3/8.
a+b
(a+b)*c+d
(a+b)÷d
(b+d)+(c÷d)
(a+b)+c
(b×d)+(c÷d)
(a+b)×(c+d)
(c+a-b)÷(b-d)
(b×d)÷(a+b)

Answer 1

a+b= 3/5+8/3=49/15
(a+b)*(c+d)= 49/5*43/8=2017/40=52.6
(a+b)/d= 49/5/3/8=392/15=26.13
(b+d)+(c/d)=73/24+40/3=131/8=16.37
(b*d)=+(c/d)=1+40/3=43/3
