Add. Write the answer in simplest form.
1. 3/8 + 4/5=
3/8=15/40
4/5=32/40
15/40 plus 32/40=47/40
47/40=1.175
Please let me know if I got the correct answer or if I did something wrong.
Usually, when the directions say "simplest form," they want a fraction.
47/40 = 1 7/40
I think I somewhat understand
To add fractions, you need to find a common denominator for the fractions you want to add. In this case, the least common multiple of 8 and 5 is 40.
To convert 3/8 to an equivalent fraction with a denominator of 40, you multiply both the numerator and denominator by 5. This gives you 15/40.
To convert 4/5 to an equivalent fraction with a denominator of 40, you multiply both the numerator and denominator by 8. This gives you 32/40.
Now, you can add the two fractions: 15/40 + 32/40.
When the denominators are the same, you simply add the numerators and keep the common denominator: 15 + 32 = 47. So, the sum is 47/40.
To simplify the fraction, you need to divide both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 47 and 40 is 1.
So, the simplest form of 47/40 is 47/40.
Therefore, your answer is correct: 47/40 or 1.175.
