The second step is to calculate the percentage of each part in the mix. Start by adding up each part in the ratio to find the total number of parts. For instance, for the M5 1:5:10 mix ratio, add up the cement, sand, and gravel parts like this: 1:5:10 mix -> 1 + 5 + 10 = 16 parts. So, in the M5 mix, there are 16 total parts.
