Question 26706: 9.2% of 180 is what number?

110% of 30 is what number?

15 is 25% of what number?

99 is 180% of what number?

32.4 is 455 of what number?

What percent of 7.2 is 45?


What percent of 3 is 150?

What percent of 50 is 250?

0.06x = 120

0.21x = 1.2 - 0.15x


0.05a + 0.5a = 4.4

0.4x + 0.24(x - 5) = 0.08

0.05x + 0.065(500 - x) = 295

You can put this solution on YOUR website!
The formula you want to use is
+%28is%2Fof%29+=+%28%22%25%22%2F100%29+ the 100 never changes and you substitute the values into the spots, for example number 1 is 9.2% of 180 is what number?


9.2 is your %
180 is your of because is has of before it
and you don't know your is, so thats your unknown


Plug it into your forumla
+%28+x+%2F+180+%29+=+%28+9.2+%2F+100+%29+
Get out your calulator and cross multiply
+100x+=+180%289.2%29+
+100x+=+1656+
+x+=+16.56+
Do the same for all the rest.


Your last questions are just solving equations like the ones we did in the example.
