Question

$\text{Linda}$ walked $2.75$ miles on the first day and $3.50$ miles on the second day. What was the total distance she walked?

• A. $6\frac{1}{4}$
  
• B. $4\frac{3}{4}$
  
• C. $12\frac{1}{2}$
  
• D. $3\frac{1}{8}$
  

Answer 1

The correct option is A $6\frac{1}{4}$


Step 1: First, convert the distances walked into mixed numbers.
$2.75=2+0.75=2+0.75\times \frac{100}{100}=2+\frac{75}{100}=2+\frac{3}{4}2.75=\frac{11}{4}$
And,
$3.5=3+0.5=3+0.5\times \frac{10}{10}=3+\frac{5}{10}=3+\frac{1}{2}$
So,
$3.5=\frac{7}{2}$

Step 2: Now,
Total distance walked by Linda $=\frac{11}{4}+\frac{7}{2}=\frac{25}{4}=6\frac{1}{4}miles$
