Answer:
Your answer is -19/15 .See how :-
Step-by-step explanation:
15/9 x (- 2/3) - 7/3 x 15/9 + 2/5.
In multiplication, cancel the numerator by denominator when possible. See
5/9 x (- 2/1) - 7/1 x 5/9 + 2/5.
Firstly solve multiplication :
-10/9 - 7/1 x 5/9 + 2/5
- 10/ 9 - 35/9 + 2/5 .
Now solve the addition. First take the LCM of 5 and 9, that is 45.
After the LCM, make the numerator as the number of times its denominator is multiplied.
- 10/9 - 175/45 + 18/45
= -10/9 - 157/45 .
Keep checking for signs for each time.
Now, Finally subtract the integers.
Take the LCM. The LCM of 9 and 45 is 45.
So, -50/45 - 157/45 = - 207/45.
At last, simplify the answer to its lowest form.
That is : - 207/45 = - 23/5. When numerator and denominator are divided by 9.
