Which is the best stock you can invest now in 2021, or where I can learn to invest in stock market​
AlladinOne [14]
There really is no ‘best stock’ to invest in. But some good stocks to invest in are Amazon, Disney, and Apple. All are companies that have had tremendous growth and appear to still be growing. You can also go onto Yahoo finance, they will tell you whether they think the stock is over priced and you can also see the growth pattern over time.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.

13 1/10-7 9/10<br><br> i need help
a_sh-v [17]

Answer:

52/ 10 = 5 2/10 or 5 1/5

Step-by-step explanation:

first turn the mixed fractions into improper fraction

13 1/10= 131/10

7 9/10= 79/10

since the two fractions already have a common denominator just subtract

131 - 79 = 52

52/ 10 = 5 2/10 or 5 1/5
