Answer: $\frac{16}{21}$

Step-by-Step Explanation:

KCFmeans: Keep, Change, Flip

Keep: the first fraction

Change: the sign from division to multiplication

Rewrite each division problem as a multiplication problem and solve. 6.3 divided 0.9 equals what

Masteriza [31]

You can write both numbers as fractions:

$6.3=\dfrac{63}{10},\quad 0.9=\dfrac{9}{10}$

Dividing by a fraction is the same as multiplying by its inverse, so we have

$\dfrac{63}{10}\div \dfrac{9}{10}=\dfrac{63}{10}\cdot\dfrac{10}{9}$

We can cross-simplify the 10's and we have

$\dfrac{63}{10}\cdot\dfrac{10}{9}=\dfrac{63}{9}=7$

6 less than the product of a number and 3 is -18..what is the number?

seropon [69]

The product of a number and 3 can be represented as 3n (where n = unknown number). Then 6 less than 3n is 3n - 6.

3n - 6 = -18
3n = -12
n = -4

Check:
-4 x 3 = -12
-12 - 6 = -18 (this works!)
