Answer:

I really hope this helps you a lot!!

7/26 * 39/-25

1. Apply the fraction rule ; a/-b = -(a/b)

7/26 * (- )

2. Get rid of the bracket;

- ( 7/26 * 39/25)

3. Make it -( (7 * 39)/(26 * 25)  *The first bracket is to indicate that the minus sign is for the whole equation*

"This is basically joining the division lines together"

4. Now Factor 39 in the numerator

= 3*13

so numerator becomes  7 * 3 * 13

5. Then Factor  26 in the denominator

= 13 * 2

So denominator becomes  2 * 13 * 25     *No need to factor the 25 cos its factors can't cancel any number in the numerator*

6. So now, we have ( 7 * 3 * 13)/(2 * 13 * 25)

so we cancel the 13 from the top and the bottom

7. So we have (7 * 3)/ (2 * 25)

8. Calculate like normal multiplying fractions ( multiply the numerators together and do same for the denominators  too)

7 * 3 = 21

2 * 25 = 50

9. So our final answer is 21/50
