Acake has a mass of 2.5kg. it contains 275g of fruit. what percentage of fruit is there in the cake

The answer is:  "11 %" . 

There is 11% of fruit in the cake.

Explanation:


275g is what percent of 2.5 kg?  

First, convert "275 g" into "kg".

Note the exact conversion:  1000 g = 1 kg .  

So 275 g = (275/1000) kg  = 0.275 kg .

0.275 kg = (n/100) * 2.5 kg ; 

→ (n/100) * 2.5 = 0.275 ;

Divide each side by "(2.5)" 

→ (n/100) = (0.275) / (2.5) ;

→ (n/100) = 0.11 ;

Multiply each side by "100" ; 

n = 11 . 

The answer is:  11 % .
