Question

X/5=4/3, atunci numărul x+5/5 este egal cu...

Answer 1

$\rm \frac{x}{5}=\frac43 \rightarrow x=\frac{5*4}{3}=\frac{20}{3} \\ \\ \frac{x+5}{5}=\frac{\frac{20}{3}+^{(3}5}{5}=\big(\frac{20}{3}+\frac{15}{3}\big)*\frac15 \\ \\ =\frac{35}{3}*\frac{1}{5}=\frac{35}{15}^{(5}=\boxed{\frac73}$

Answer 2

in cadrul temei " proportii derivate" , ati invatat ca

a/b = c/d => (a+b)/b = (c+d)/d

x/5 = 4 / 3 

(x+5)5= (4+3)/3 = 7/3
