Answer:
No 27/51 is greater than 18/34.
Step-by-step explanation:
If you simplify 27/51. It'll be 3/7 and if you simplify 18/34 it will be 9/17. Multiply the two fractions but not across. multiply the denominator with the numerator and the other numerator to the denominator to get 63 on 9/17 and 51 on 3/7. So 27/51 > 18/34.
Nine times thirty-eight can also be thirty-eight times nine or (18 divided by 2) multiplied by 38 or like this
(18/2)times(38/2)
I hope this gives you an idea
I think 140 is the answer
1 lb / 0.45 = 2.22
so approximately 2.22 kilograms per pound
divide price per pound by kilometers per pound
1.44 / 2.22 = 0.648
round to 0.65, so it costs $0.65 per kilogram
