You need to make both numbers the same denominator (bottom number). Do this by multiplying. So for the first question you need 15 as the denominator. 3x3=9 5x3=15 first one is 9/15. Then its 1x5=5 and 3x5=15. Then you add 9+5 to get 14. The denominator stays the same. 14/15. This cannot be reduced. If reduced, you would be able to divide both numbers by the same number.
1. 14/15
2. 5/6
3. 1/2
4. 13/24
5. 13/24
6. 9/10
7. 5/9
8. 11/35
9. 5/8
10. 1/2

without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90
yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram
