difference means subtract
Basically, 27.7% of 970 is 268.69 grams, if 13 minutes so i’m pretty sure it’s 268.69 X 13 = 3492.97, it cannot be deduced from 970 unless it became −2522.97, is that the answer ur looking for?
13,because it’s the single number that divides with 52
52:13=4
Ok, i really don't remember this, so i don't want to steer you wrong. maybe wait for another answer?
