Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2?

Answers

Because 1/2 of 6 =1/3 and 1/2×1/3=1/6
The number 3 can be expressed as a fraction 3/1. If we multiply the fraction 1/6 by 3/1 we get:
1/6 x 3/1 = (1 x 3)/(6 x 1)
(1 x 3)/(6 x 1) = 3/6
Now just simplify the fraction:
3/6 = 1/2

What is the quotient of 5.4 and -0.3

Answers

Hey there!

The "quotient" is basically the result of a division equation

Remember: \n -,- = + \n +,+ = + \n-,+ = - \n +,- = -

This pair is: +, - (Positive (+), negative (-)

So, this means your result will be a negative

(5.4)/(-0.3) = -18 \n \n (-0.3)(-18) = 54 \n -18 = -18

Therefore your quotient is -18

Good luck on your assignment and enjoy your day!

Hello!

If you divide or multiply by one negative number, the number will remain negative. Let's just divide 5.4 and 0.3, and add a negative after.

5.4/0.3=18

We add our negative

-18

Therefore, our quotient is -18.

I hope this helps!

Grady marks down some $2.49 pens to $1.99 for a week and then marks them back up to $2.49. Find the percent of increase and the percent of decrease to the nearest tenth. Are the percents of change the same for both price changes? If not, which is a greater change

Answers

$2.49 -------------------100 %
$1.99 ------------------- x %
-------------------------------------
2.49 : 1.99 = 100 : x
x = ( 1.99 * 100 ) / 2.49 = 79.9 %
100 % - 79.9 % = 21.1 % ( Decrease )
$1.99 -------------------- 100 %
$2.49 -------------------- x %
------------------------------------
1.99 : 2.49 = 100 : x
x = ( 2.49 * 100 ) / 1.99 = 125.1 %
125.1 % - 100 % = 25.1 % ( Increase )
The percents of change are not the same.
The greater change is during the increase of price ( 25.1 % > 21.1 % ).
