Ihave no idea on how to proceed with literal equations. i can do regular linear equations, but this just stumps me! give a detailed explanation? : )

do you have a picture of the table

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

answer:
