It's amazing how important things like Geography and Grammar were in fifth grade. Remember when you had to know the answers by heart? But today, things are different with google maps, calculators and spell check. The knowledge you used to be proud to have, have lost their usefulness. When was the last time your boss asked you to name the capitals of each state? How about to multiply 12 X 14 without a calculator? Thought so. In other words, it's not that ridiculous that a fifth grader might be able to blow you away by answering these questions better and faster than you.Â
But you have your pride. No fifth grader is going to show you up. But before you take this to the playground, maybe you should take this quiz and see how you compare to a fifth grader. But be forewarned, you'll be asked questions where no calculator can be used -- that includes questions with percentiles and decimals. Plus, there are questions on mnemonics for remembering the correct order of arithmetic operations, and ordered pairs. Ready? Then get out your No. 2 pencil, put your books away and start on this 15-question quiz now. Or simply click on the correct answer. Either way, we'll give you a gold star for trying.Â
5 + 7 + 10 + 6 - 2 = ?
13
12
39
26
For this question, it's necessary to add and subtract numbers as indicated to find the total. 5 + 7 = 12, 12 + 10 = 22, 22 + 6 = 28, and 28 - 2 = 26.
On a number line, which number is closest to zero?
-77
+988
-2
A number line can be drawn according to the scale of the problem at hand, but all numbers are a certain distance from zero. Small positive and negative numbers are closest to zero, while large positive and negative numbers are farther away.
'Centi' stands for one hundred. There are one hundred centimeters in a meter, and 0.01 meters in one centimeter. Similarly, there are 1,000 millimeters in one meter and 0.001 meters in one millimeter.
Using the correct order of operations during basic arithmetic
PEMDAS is a mnemonic for remembering the correct order of operations. It means to first simplify anything inside parentheses, then simplify exponents, then multiply and divide, then add and subtract.
In a fraction, the numerator is the place for the top number and the denominator is the place for the bottom number. For example, in the fraction 1/4, 1 is in the numerator and 4 is in the denominator.
What answer should you get when dividing 1.4 by 0.7?
0.2
2
An interesting way to think about this problem is to turn it into (1.4/0.7) x (10/10). 1.4 x 10 = 14 and 0.7 x 10 = 7. Now, you have 14/7, which easily simplifies to 2.
Which of the following ordered pairs has the greatest x-value?
(2, 6)
(5, 5)
(-2, 7)
(14, -3)
Ordered pairs are written in the format (x,y) with respect to the x,y coordinate system. (14, -3) has the largest x value and (-2,7) has the largest y value.
The number itself doesn't give any information regarding accuracy, but as for precision, 6.7899 is by far the most precise. It is able to report information all the way to the ten-thousandths digit, which is the smallest digit shown.
What number is the result when 1090.877 is rounded to the nearest hundred?
1,090.9
1091
1,100
Rounding to the nearest hundred means finding the number closest to the next full digit in the hundreds column. Since 90 is closer to 100 than to 0, 1090.877 is rounded to 1,100.
