find 90% of 130:

Explanation:

Step1: Find 10% of 130

To find a percentage of a number, we convert the percentage to a decimal and multiply by the number. 10% as a decimal is $0.10$. So we calculate $130\times0.10$.
$130\times0.10 = 13$

Step2: Find 90% of 130

90% as a decimal is $0.90$. We can also note that 90% is $100\% - 10\%$, so we can calculate $130 - 13$ (since we already found 10% of 130 is 13) or directly calculate $130\times0.90$.
$130\times0.90 = 117$ (or $130 - 13 = 117$)

Answer:

Find 10% of 130: $13$
Find 90% of 130: $117$
