Answer: 3 7/10
Solution by separating parts
Let's rewrite our equation with the parts separated
= 1 + 2/5 + 2 + 3/10
Now, let's add the whole numbers
1 + 2 = 3
Now, let's figure out how to solve the fraction parts
2/5 + 3/10 = ?
You'll need to find the LCD (Lowest Common Denominator) of 2/5 and 3/10.
If you don't know, the LCD is 10
Since 3/10 already has a denominator of 10, we don't need to do anything with it.
However, we need to multiply the numerator and denominator of 2/5 by 2
Why? We need the LCD, which is 10. Also, we can only add fractions if they have the same denominators
Numerator: 2 x 2 = 4
Denominator: 5 x 2 = 10
Fraction: 4/10
Now add the fractions
4/10 + 3/10 = 7/10
Finally, combine the whole numbers with the fractions
3 + 7/10 = 3 7/10
