Answer:

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

Step-by-step explanation:

The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

$\frac{5}{7}+ \frac{10}{1} \\The \ LCM \ is \ 7\\\\= \frac{5(1)+10(7)}{7}\\\\= \frac{5+70}{7}\\\\= \frac{75}{7} \\\\= 10 \frac{5}{7}$

Hence the expression written in equivalent form of common denominator is $\frac{5 + 70}{7}$

The sum is $10 \frac{5}{7}$
