Question

In a fabric, silk and poly - silk fibers are in the ratio of 2:3. What is the percentage of poly-silk fibre in the fabric ?​

Answer 1

Answer:

60%

Step-by-step explanation:

part of silk in fabric = 2x

part of poly silk in fabric = 3x

total fabric = 2x+3x=5x

% of polysilk in fabric = (3x/5x)*100 = 3*20= 60%

% of silk in fabric = (2x/5x)*100= 2*20 = 40%
