Answer:
(-4, 2.5)
Step-by-step explanation:
-8/2=-4
5/2=2.5
It's 18/100. The reduced / simplest form is 9/50 because you divide it by 2 since it's the GCS.
1/5( 5/2 x 4/7 -11/7) + 3/28
Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.
Then multiply 1/5 with 10/7. The result will be 2/7.
2/7 + 3/28 = 11/28
