frozen [14]
To multiply fracti0ons, we need to convert them to improper fractions:

-2 1/4 = -9/4
-4 1/2 = -9/2

Now, lets multiply:

-9/4 * -9/2 = 81/8

Hope this helps!

Take note that the answer is positive because when multiplying, two negatives make a positive.

If the 10th of the 10 consecutive numbers is 10, what is their sum?
liq [111]
Represent these consecutive numbers (assuming that they are all integers):

x
x+1
x+2
x+3
x+4
x+5
and so on
x+8
x+9 is the tenth number.  x+9 = 10, so x = 9.

Think of it this way:  there are 10 consecutive numbers, and the last one is 10.

Working backwards, we get the sequence 10, 9, ... 3, 2, 1.

The sum of such an arith sequence is equal to the count of the numbers times the average of the first and last terms:

sum here = 10(1+10)/2 = 5(11) = 55          (answer)
