There are 29235 marbles and 371 jacks. If you want to know the percentage of jacks, do you divide the first number by the second
garik1379 [7]

Answer:

Correct answer: Two decimal places to the right

Step-by-step explanation:

We will set the classic proportion:

29,235   -    100%

     371    -        x%

29,235 : 371 = 100 : x  ⇒ 29,235 · x = 371 · 100

x = (371/ 29,235) · 100 = 0.0127 · 100 = 1.27%

x = 1.27%

You divide first number by the second and then multiply with 100,

which is the same as moving the decimal point two places to the right.

God is with you!!!
