A solder composition of 50/50 indicates the alloy is composed of lead and tin in what proportion?

Explanation:
A 50/50 solder means equal parts of lead and tin. Half of the alloy’s composition is lead and the other half is tin, by weight. Because the ratio is equal, you have 50% lead and 50% tin. The other options show uneven distributions (more lead than tin or more tin than lead), which do not fit a 50/50 mix.
