I don’t know exactly but I tried the math and it’s either 4 or 5%
Answer:
according to the ratio, if every other chocolates Jodi ate is 36.5 calories, then if she ate 5 chocolates then she would have eaten 157.5 calories. What varies means is some chocolates may not exactly be 36.5 calories.

Answer:
12/19 or 0.6315
Step-by-step explanation:
You see that the denominator of 3/4 is 4 and the numerator of 16/19 is 16 both 4 and 16 are common factors, so you can reduce this to 3x4/19 then multiply 3/1 x 4/19 to give you 12/ 19 because 3x4 is 12 and 1x19 is 19.
Position in the sequence triangular number relation
1 1 1 = 1*(1+1)/2
2 3 3 = 2(2+1)/2
3 6 6 = 3(3+1)/2
4 10 10 = 4(4+1)/2
5 15 15= 5(5+1)/2
Call n the position in the sequence, then the triangular number is: n(n+1)/2
