Glenn Beasley · Answer 1

Assuming Jenny baked 15 cookies, we can make a percentage by first making a fraction.

So we would write 15/50 since they made 50 cookies total.

Now let's write 15/50 as a fraction over 100. That would be 30/100 when we multiply the top and bottom by 2. 30/100 as a percent would be 30 percent of all cookies.

Kiana · Answer 2

To find the percentage of cookies baked by Jenny we first have to know how many cookies total there were. 15+18+17=50 cookies all together. The question is asking us "what percentage" (x) "of" (multiply) 50 "is" (equals) 15? Using the variables and numbers only our questiion becomes 50x = 15. Divide both sides by 50 to get x =.3. Since this value is a percentage, we find that percentage by multiplying by 100. 30%.
