7x2=14

answer is 14

7:26

Step-by-step explanation:

Hey there!

You could represent this situation by putting the calories of one snack on one side of the ratio and doing the same with other snack on the other side:

35:130, meaning that for every 35 calories an orange has, a cookie has 130 calories

You could simplify this by dividing both numbers by 5.  

7:26, meaning that for every 7 calories an orange has, a cookie has 25 calories

Hope this helped you out! :-)
