4/5+7/15+3/5
To add fractions, we need to find a common denominator. In this case, the common denominator is 15.
Converting the fractions to have a denominator of 15:
4/5 = (4/5) * (3/3) = 12/15
7/15 = (7/15) * (1/1) = 7/15
3/5 = (3/5) * (3/3) = 9/15
Adding the fractions:
12/15 + 7/15 + 9/15 = (12 + 7 + 9)/15 = 28/15
Therefore, 4/5 + 7/15 + 3/5 = 28/15.
To solve the equation 4/5 + 7/15 + 3/5, you need to find a common denominator.
The denominators involved are 5 and 15.
To find a common denominator, you can multiply the denominators together. The common denominator for 5 and 15 is 5 * 15 = 75.
Now, you need to convert each fraction to have a denominator of 75.
For the first fraction, 4/5, you can multiply both the numerator and the denominator by 15. This gives us (4 * 15) / (5 * 15) = 60/75.
For the second fraction, 7/15, you can multiply both the numerator and the denominator by 5. This gives us (7 * 5) / (15 * 5) = 35/75.
For the third fraction, 3/5, you don't need to do anything because it already has the denominator of 5.
Now, you can add these fractions together: 60/75 + 35/75 + 3/5.
To add fractions, you need to have the same denominator. In this case, the denominator is 75, so you can add the numerators together:
(60 + 35 + 3) / 75 = 98/75.
Therefore, the sum of 4/5 + 7/15 + 3/5 is 98/75.
To solve the expression 4/5 + 7/15 + 3/5, we need to find the common denominator for all three fractions.
The common denominator is the lowest common multiple (LCM) of the denominators. In this case, the denominators are 5 and 15. The LCM of 5 and 15 is 15.
To convert each fraction, we need to multiply both the numerator and denominator of each fraction by the same value so that the denominator becomes 15.
For 4/5, multiplying both the numerator and denominator by 3 gives us (4×3)/(5×3) = 12/15.
For 7/15, we don't need to make any changes because the denominator is already 15.
For 3/5, multiplying both the numerator and denominator by 3 gives us (3×3)/(5×3) = 9/15.
Now that all three fractions have the same denominator, we can add them together.
12/15 + 7/15 + 9/15 = (12 + 7 + 9)/15
Calculating the numerator:
12 + 7 + 9 = 28
So, the expression simplifies to:
28/15
