Question

Add - 1 3/10 + ( - 4 2/15

Answer 1

The choices are -5 1/6, -5 1/5, -2 5/6, - 5 13/30

Answer 2

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

-1 3/10 can be converted to -13/10.

-4 2/15 can be converted to -62/15.

Now, we can add the fractions. (-13/10) + (-62/15) is equal to (-195/150) + (-62/15).

To add these fractions, we need to find a common denominator, which is 150.

(-195/150) + (-62/15) = (-195/150) + (-20*62/20*15)

= (-195/150) + (-1240/300)

Now, we can add the numerators.

= (-195 - 1240)/150

= -1435/150

The fraction -1435/150 cannot be simplified any further.

Therefore, the answer is -1435/150.

Answer 3

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

-1 3/10 can be converted to -13/10.

-4 2/15 can be converted to -62/15.

Now, we can add the fractions. (-13/10) + (-62/15) is equal to (-195/150) + (-62/15).

To add these fractions, we need to find a common denominator, which is 150.

(-195/150) + (-62/15) = (-195/150) + (-20*62/20*15)

= (-195/150) + (-1240/300)

Now, we can add the numerators.

= (-195 - 1240)/150

= -1435/150

The fraction -1435/150 cannot be simplified any further.

To convert -1435/150 back to a mixed number, we divide the numerator by the denominator.

-1435 ÷ 150 = -9 remainder 35

Therefore, the answer is -9 35/150.

We can simplify this mixed number by dividing both the numerator and denominator by their greatest common divisor, which is 5.

-9 ÷ 5 = -1 remainder 4

35 ÷ 5 = 7

Therefore, -9 35/150 is equivalent to -1 4/30.

Simplifying the fraction 4/30 further, we divide both the numerator and denominator by their greatest common divisor, which is 2.

4 ÷ 2 = 2

30 ÷ 2 = 15

Therefore, -1 4/30 is equivalent to -1 2/15.

Therefore, the correct answer is -1 2/15.
