Answer:
(-53)/80
Step-by-step explanation:
Simplify the following:
-23/30 + 5/48
Put -23/30 + 5/48 over the common denominator 240. -23/30 + 5/48 = (8 (-23))/240 + (5×5)/240:
(8 (-23))/240 + (5×5)/240
8 (-23) = -184:
(-184)/240 + (5×5)/240
5×5 = 25:
(-184)/240 + 25/240
-184/240 + 25/240 = (-184 + 25)/240:
(-184 + 25)/240
-184 + 25 = -159:
(-159)/240
The gcd of -159 and 240 is 3, so (-159)/240 = (3 (-53))/(3×80) = 3/3×(-53)/80 = (-53)/80:

9 7/8 written as a decimal is 9.88
Work: So, The first thing I did was 9 (Whole Number) times the Denominator. After the Multiplication, I had gotten 72. I added 72 by the numerator which is 79. Then, I divided 79 by the denominator, and I had gotten 9.875, and I rounded it up to 9.88
I hope this helps, and you get this question correct. :)
She worked 50.5 hours last week.
7.80x40=312
352.95-312=40.95
40.95/4.90=10.5
10.5+40=50.5
