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.
Hope This Helped :)
