add - 1 3/10 + (-4 2/15)
To add - 1 3/10 and -4 2/15, we need to find a common denominator for 10 and 15, which is 30.
- 1 3/10 is equivalent to -13/10.
-4 2/15 is equivalent to -62/15.
Now, we can add:
-13/10 + (-62/15)
To add fractions, we need to have the same denominator. In this case, the denominators are already the same, so we can simply add the numerators:
-13 + (-62) = -75
Thus, the sum is -75/15.
We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor (5):
-75 ÷ 5 = -15
15 ÷ 5 = 3
So the simplified fraction is -15/3, which can be further simplified to -5.
Therefore, - 1 3/10 + (-4 2/15) is equal to -5.
is it -5 1/5
Apologies for the mistake in the previous response. Let's re-calculate:
To add -1 3/10 and -4 2/15, we'll find a common denominator of 30.
- 1 3/10 is equivalent to -13/10.
- 4 2/15 is equivalent to -62/15.
Now, we can add:
-13/10 + (-62/15)
We need to have the same denominator to add the fractions. The least common multiple of 10 and 15 is 30, so let's rewrite the fractions with a common denominator of 30:
-13/10 = -39/30
-62/15 = -124/30
Now, we can add the fractions:
-39/30 + (-124/30)
Adding the numerators:
= -39 + (-124)
= -163
So, the sum is -163/30.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (gcd), which is 1 in this case since there are no common factors:
-163 ÷ 1 = -163
30 ÷ 1 = 30
Thus, the simplified fraction is -163/30.
To convert this improper fraction to a mixed number, we divide the numerator by the denominator:
-163 ÷ 30 = -5 remainder 13
The whole number part is -5, and the remainder 13 is the numerator of the fraction. The denominator remains the same. Therefore, the sum is -5 13/30.
Therefore, -1 3/10 + (-4 2/15) equals -5 13/30.
add -1.2 + 7.6
To add -1.2 and 7.6, we simply add the two numbers:
-1.2 + 7.6 = 6.4
Therefore, -1.2 + 7.6 equals 6.4.
add -4.85 + (-2.54)
To add -4.85 and -2.54, we simply add the two numbers:
-4.85 + (-2.54) = -7.39
Therefore, -4.85 + (-2.54) equals -7.39.
add 4.6 + (9.04).
To add 4.6 and 9.04, we simply add the two numbers:
4.6 + 9.04 = 13.64
Therefore, 4.6 + 9.04 equals 13.64.
