What is the underlined digit?

how do you do percent proportions? I'm learning those right now, and I have no idea what to do. my teacher isn't the best at explaining things. an example of what I don't get is "4% of what number is 10?" also things such as "16 is what percent of 64?"

Answers

Remember these tips:

=> To turn apercent into a decimal, move the decimal point 2 places to the left.
4%means 0.04 , and 50% means 0.5 .

=> To turn a decimal into percent, movethe point 2 places to the right.
0.062 means 6.2% .

=> Inmath, whenever you see the word "of", it almost always means "times".
So your 2nd example means

16 = (mystery number) x (64).

Divide eachside by 64 : 16/64 = mystery number = 1/4 = 0.25 .

Move the point 2places to the right. 0.25 = 25% .

If J = 12 then J/3 + 3 What is J

Answers

Well, you're given that $J=12$ . I think the extra information is extraneous, unless there's something more that you forgot to add.
Hope I could be of some assistance. :)

Well i think your asking what is J divided by 3+3 which is 4+3 =7 or IF multiplying which is 36 +3= 39
