Its 5. Since -9 + 8 is in parentheses, you do that first and you should get -1. Finally you add 6 and -1 and you get 5, because you count -1 by 6 since its adding on the number line. Like this, -1, 0, 1, 2, 3, 4, 5. So, the final answer is 5.

What is 7/12 divided by 14/15

Answers

STOP- DROP(The division sign)- FLIP(the fraction being divided- 2nd fraction)!

So, it would be 7/12 * 15/14= 105/168 - simplifies to 5/8

Just remember stop drop flip!

Dividing the fraction 7/12 by 14/15 will give us 5/8. This is done by multiplying the first equation with the reciprocal of the second before dividing with their common divisor

How do we divide fraction?

When you divide by a fraction, it's the same as multiplying by its reciprocal. The reciprocal of a fraction is created by switching the numerator and the denominator.

So the reciprocal of 14/15 is 15/14.

Therefore, the division problem

7/12 ÷ 14/15

can be rewritten as

7/12 × 15/14.

Performing this multiplication gives:

(7 × 15) / (12 × 14)

= 105 / 168

= 5/8

Note that this fraction (105 / 168) can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 21, to get:

105/21 / 168/21 = 5/8
