13/20-3/10
estimate:
closer to 1 or 0?

So, what you need to is find the decimal or percent of them. So 13/20 is 65% or. 65. You get that buy multiplying it by 5 to get the denominator of 100. A denominator can go up to 100. 13/20 is closer to 1 because 65% is closer to 100% than 0%. Next 3/10 is 30%. Do that by multiplying it by 10 to get the denominator of 100. 30% is closer to 0 than 100%. Subtract them. 1-0= 1. The answer is 1.

\( \frac{13}{20}<\frac{14}{20} =\frac{7}{10}\ \ \ and\ \ \ \frac{13}{20}>\frac{12}{20}=\frac{6}{10}\\ \\\frac{6}{10}<\frac{13}{20} <\frac{7}{10}\ \ \ \Rightarrow\ \ \ \frac{6}{10}-\frac{3}{10}<\frac{13}{20}-\frac{3}{10} <\frac{7}{10}-\frac{3}{10}\\ \\ \frac{3}{10} <\frac{13}{20}-\frac{3}{10} <\frac{4}{10}\\ \\Ans. \ \frac{13}{20}-\frac{3}{10} \ is\ closer\ to\ 0 \)
