Add −1 3/10 +(−4 2/15)
To add -1 3/10 and -4 2/15, we first need to convert both mixed numbers to improper fractions.
-1 3/10 can be written as -10/10 + 3/10, which equals -13/10.
Next, we convert -4 2/15 to an improper fraction. -4 2/15 can be written as -60/15 + 2/15, which equals -58/15.
Now we can add the two fractions:
-13/10 + (-58/15)
To add these two fractions, we need a common denominator. In this case, the least common multiple (LCM) of 10 and 15 is 30.
Next, we convert both fractions and add them:
(-13/10)×(3/3) = -39/30
(-58/15)×(2/2) = -116/30
Now, we have:
-39/30 + (-116/30)
Combining the fractions:
-39 - 116 = -155
The denominator remains 30.
Therefore, -1 3/10 + (-4 2/15) is equal to -155/30, which can be further simplified to -31/6.
-1 3/10 can be written as -10/10 + 3/10, which equals -13/10.
Next, we convert -4 2/15 to an improper fraction. -4 2/15 can be written as -60/15 + 2/15, which equals -58/15.
Now we can add the two fractions:
-13/10 + (-58/15)
To add these two fractions, we need a common denominator. In this case, the least common multiple (LCM) of 10 and 15 is 30.
Next, we convert both fractions and add them:
(-13/10)×(3/3) = -39/30
(-58/15)×(2/2) = -116/30
Now, we have:
-39/30 + (-116/30)
Combining the fractions:
-39 - 116 = -155
The denominator remains 30.
Therefore, -1 3/10 + (-4 2/15) is equal to -155/30, which can be further simplified to -31/6.
−1.2+7.6.
To add -1.2 and 7.6, we simply add the decimal numbers:
-1.2 + 7.6 = 6.4
-1.2 + 7.6 = 6.4
−4.85+(−2.54)
To add -4.85 and -2.54, we simply add the decimal numbers:
-4.85 + (-2.54) = -7.39
-4.85 + (-2.54) = -7.39
4.6+(−9.04)
To add 4.6 and -9.04, we simply add the decimal numbers:
4.6 + (-9.04) = -4.44
4.6 + (-9.04) = -4.44
