What helps to remember distributive property

If you can remember that multiplication distributes over addition, that will kinda help you.
Example
2(3+4)=2x3+2x4
I hope this helps

That’s what i got when i looked up what the solutions were

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
