To find the sum of the fractions 4/5 + 7/10, you first need to find a common denominator. A common denominator is a multiple of both denominators. In this case, we can see that 5 and 10 have 10 as a common multiple.
To convert 4/5 to an equivalent fraction with a denominator of 10, you can multiply both the numerator and denominator by 2. This gives us (4 * 2) / (5 * 2) = 8/10.
Now we can rewrite the expression as 8/10 + 7/10.
Since the denominators are now the same, we can simply add the numerators. 8 + 7 = 15.
Therefore, the sum of 4/5 + 7/10 is 15/10.
However, this fraction can be further simplified. Since 15 and 10 have a common factor of 5, we can divide both the numerator and denominator by 5. This gives us (15 ÷ 5) / (10 ÷ 5) = 3/2.
So, the answer to the fraction 4/5 + 7/10, after simplification, is 3/2.
