3.5 cm is 5 times as long as 7 mm, and 4 times longer than 7 mm.
pH is amplified in logs of 10. For example, a reading of 6 pH is 10 times more acidic than that of 7 and 6 pH is 100 times more acidic than 8 pH. Since 7-3=4, a pH of 3 is 104 or 10,000 times more acidic than a pH of 7.
Expressed algebraically, this is equal to 3x + 7.

2 times 3 = 6 which is less than 7 or 1 times 3 = 3 which is less than 7
Yes. 7 is more than 3.
10 is 7 more than 3
The number 21 is 3 times as large as 7. 7 x 3 = 21

1 is most acidic 3 is to less than that 7 is netrul

no 3/7 is less than half 7/3 is more than two 3/7 x 3/3 = 9/21 7/3 x 7/7 = 49/21
