Answer:
Step-by-step explanation:
Given
The ratio of mixture of sand and cement is 5:3
If the total volume of mixture is
Suppose there is 5x and 3x cubic centimeter of sand and cement respectively i.e.
Sand
So, there is of sand in the mixture
A ratio equivalent to 3/20 can be 6/40 or even 9/60
The answer is k-20
decreased means to take away/subtract, “k” is being subtracted by 20, therefore k-20
Hope this helps! have a wonderful day!
