what is -18/15+4/15
To solve the expression -18/15 + 4/15, you need to find a common denominator for the two fractions. Both fractions have a denominator of 15, so you can directly add the numerators together:
-18/15 + 4/15 = (-18 + 4)/15 = -14/15
Therefore, -18/15 + 4/15 is equal to -14/15.
whats−1 3/10 +(−4 2/15).
To solve the expression -1 3/10 + (-4 2/15), we first need to convert the mixed numbers to improper fractions.
-1 3/10 is equivalent to -10/10 + 3/10, which simplifies to -13/10.
-4 2/15 is equivalent to -60/15 + 2/15, which simplifies to -58/15.
Now that we have the fractions, we can add them together:
-13/10 + (-58/15)
To add the fractions, we need a common denominator, which is 10 * 15 = 150.
(-13/10) * (15/15) = -195/150
(-58/15) * (10/10) = -580/150
Now we can add the two fractions:
-195/150 + -580/150 = (-195 - 580)/150 = -775/150
The fraction -775/150 cannot be simplified further, so -1 3/10 + (-4 2/15) is equal to -775/150.
To solve the expression (-18/15) + (4/15), follow these steps:
Step 1: Find a common denominator for the fractions -18/15 and 4/15. Since the denominators are already the same, which is 15, no further action is needed.
Step 2: Add the numerators of the fractions: -18 + 4 = -14.
Step 3: Keep the common denominator and simplify the numerator: -14/15.
Therefore, the simplified answer is -14/15.
