Answer:
[tex]\frac{43}{100}[/tex]
Step-by-step explanation:
[tex]\frac{4}{10}+\frac{3}{100}[/tex]
What we're going to want to do here is make the bases (the bottom numbers) equal to each other before you add.
We do this by multiplying 4/10 by 10/10, which we can do because we're technically multiplying something by 1, which doesn't ever change anything.
[tex](\frac{4}{10}*\frac{10}{10})+\frac{3}{100}[/tex]
simplify
[tex]\frac{40}{100}+\frac{3}{100}[/tex]
Now that the bases are the same, we can add the top values.
[tex]\frac{40}{100} +\frac{3}{100}=\frac{43}{100}[/tex]
