Answer:
24/35
Step-by-step explanation:
1) Convert your mixed number (1 and 1/7) to an improper fraction by multiplying your whole number (1) and your denominator (7) which gives you 7. Then add your numerator (1) to that which gets you 8. Then take the original denominator (7) and turn it into improper where your new numerator is 8 and your denominator stays 7. (If that doesn't make much sense then you can look up how to change mixed numbers into improper fractions.)
2) Multiply your numbers straight across.
8/7 * 3/5
8*3= 24
7*5= 35
24/35 you can't simplify this, so 24/35 is your answer
255.00 x 0.40 % = 102.00
102.00 +255.00 = 357.00 (original price of tv)
