Answer and explabation:
If you multiply both 3 and 8 by the same number, you get an equivalent rate to 3:8.
For example, multiply both 3 and 8 by 5.
3 * 5 = 15;
8 * 5 = 40.
The rate 15:40 is equivalent to 3:8.
Since there is an infinite number of different numbers that you can multiply both 3 and 8 by, there is an infinite number of equivalent rates to 3:8.
The multiplication tables do not go only to 9. We only normally memorize the multiplication tables to 9 or 10 because that allows you to do any multiplication on paper. If you want, you can write the multiplication tables to 100 or 1000 or any other number you choose. There is an infinite number of multiplication tables, but we only use very few of them.
Answer: 440 grams for 1.54 is the better value

Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
