12.5% of an amount is 25 grams. find the full amount.

if you multiply 12.5% by 4 you get 50%, and 100 grams. Then if you multiply that by 2 more, you get 10% and 200 grams.

Step-by-step explanation:

i'm sure goog can you get that answer

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
