Add −8/15+4/15.(1 point)

Question

A = 4/15

B= -2/15

C = 4/5

D = -4/15

Answer 1

To add -8/15 and 4/15, we simply add their numerators and keep the denominator the same:

-8/15 + 4/15 = (-8 + 4)/15 = -4/15

Therefore, the answer is D, -4/15.

Answer 2

Add −1 3/10 +(−4 2/15).(1 point)

A = -2 5/6

B = -5 13/30

C = -5 1/5

D = -5 1/6

Answer 3

To add -1 3/10 and -4 2/15, we need to first convert the mixed numbers to improper fractions:

-1 3/10 = -10/10 + 3/10 = -13/10

-4 2/15 = -60/15 + 2/15 = -58/15

Now we can add the fractions by finding a common denominator:

-13/10 + (-58/15) = (-13*3)/(10*3) + (-58/15) = -39/30 - 58/15

To combine the fractions, we need to have the same denominator:

-39/30 - 58/15 = -39/30 - (2*58)/(2*15) = -39/30 - 116/30

Now, we can combine the numerators:

-39/30 - 116/30 = (-39 - 116)/30 = -155/30

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 5:

-155/30 = -31/6

Therefore, the answer is D, -5 1/6.

Answer 4

Add −1.2+7.6.(1 point)

A = 8.8

B = -6.4

C = -8.8

D = 6.4

Answer 5

To add -1.2 and 7.6, we can simply add the numbers:

-1.2 + 7.6 = 6.4

Therefore, the answer is D, 6.4.

Answer 6

You got question 2 wrong

it was actually B = -5 13/30

Answer 7

Apologies for the mistake. Let's add -1.2 and 7.6 correctly.

-1.2 + 7.6 = 6.4

Therefore, the answer is D, 6.4 is the correct answer.
