Which of the following is the best estimate for 31% of 9? *GIVING 99 Points!*
Marina CMI [18]
Hello! So, when you know your fractions and percents, you know that about 33% equals 1/3. 31 is close to 33, so the best estimate for 31% of 9 is 3. When you solve it on a calculator, 9 * 31% (0.31) is 2.79, which rounds off to 3 when rounded to the nearest whole number. The answer is B: 3.

I am weighed on scales which have a 10% error, that is, the scales show me 10% heavier than my real weight. If I actually weigh
stiks02 [169]
Remember you said the scale shows you 10% heavier.

So that's an increase of 10%

So value = 10% + 100% = 110%

So scale would show  110% of 82

110% of 82

= (110/100)  * 82

= 1.1 * 82

= 90.2

OR

We can simply find 10% of 82 and add it to the original 82.

10% of 82

(10/100) * 82

0.1 * 82 = 8.2

8.2 + 82 = 90.2    Same answer as before.

So scale shows 90.2 kg.
