Exactly the same way you would do it if it were a proper fraction . . .
multiply the numerator by the whole number, and then clean up
the fraction.

Turn the whole number into a fraction and then multiply straight across
EX: 3 times 15/10
Change 3 into 3 over 1 3/1
All you have to do next is multiply 3 by 15 and 1 by 10
3 times 15 is 45 and 1 times 10 is 10
The improper fraction after multiplying is 45/10
If you wanted to simplify that it would be 4 1/2

How do work this out

BabaBlast [244]

We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35.

Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.

So split the 2r into these two terms and group.

(5r^2 - 5r) + (7r - 7)

Factor both groups.

5r(r-1) + 7(r-1)

The factors of (r-1) can be added together to get the answer.

(r-1)(5r+7)

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

$0.0007 - (4.9\times 10^{-7} )$
$4.9\times10^{-7} =0.00000049$
$0.0007-0.00000049$
$0.0007-0.00000049=0.00069951$
$=0.00069951$
$0.00069951=6.9951 \times10^{-7}$
$=6.9951 \times10^{-7}$

Your answer is "6.9951 × 10^-7" or option B.

Hope this helps.
