Question

len walks 3/10 mile in the morning and 2/5 mile in the afternoon
len says that he walks a total of 5/15 mile in the morning and afternoon

Answer 1

Hey There!

Steps to solve (Please note, steps will be in numerical order.)


1.To start off you have to find the lCD of $\frac{3}{10}$  and $\frac{2}{5}$ . So, the LCD of both fractions is ten.

2. Now, rewrite the fraction $\frac{3}{10}$ to $\frac{4}{10}$ , since the lcd is 10 you have to multiply the numerator and denominator of $\frac{2}{5}$ by two.

3. You only have to add $\frac{3}{10}$ + $\frac{4}{10}$

4. First, add the numerators 3+4 which is 7. Remember when adding fractions the denominator stays the same.

5. In conclusion, you're final answer should be $\frac{7}{10}$, so Len's statement was false and he walked total $\frac{7}{10}$ steps.
