Answer:
2/5 + 5/10 = 9/10
Step-by-step explanation:
Turn 2/5 into 4/10 to make the two fractions' denominators the same by multiplying 2 × 2 =4 and 5 × 2 = 10. Then add 4/10 + 5/10 to get 9/10.
Answer:
![\frac{9}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D)
Step-by-step explanation:
Find the LCD because like last time, you cannot add or subtract fractions with different denominators.
LCD = 10
Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.
![\frac{2 * 2}{5 * 2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20%2A%202%7D%7B5%20%2A%202%7D)
![\frac{4}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D)
![\frac{4 + 5}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%2B%205%7D%7B10%7D)
![= \frac{9}{10}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B9%7D%7B10%7D)
