Talia would need 15 strawberries and 6 oranges. This is solved by cross multiplication. (S)trawberries explanation:

S will be what is multiplied by 8 which will get us the same product of 10 * 12, which is 120. S will be our answer for the strawberries.
S' solution: S =

→ S =

S = 15
Therefore S is 15. (O)ranges explanation:

Same thing applies, but this time we need the number O equals when multiplied by 8, will get us the product of 12 * 4, which is 48.
O's solution: O =

O =

O = 6
Therefore O is 6.
