Answer:

4=x

Step-by-step explanation:

x+10= 4x-2

Subtract x from each side

x-x+10 = 4x-x-2

10 =3x-2

Add 2 to each side

10+2 = 3x-2+2

12 = 3x

Divide by 3

12/3 = 3x/3

4 = x

4/9÷1 7/15
guajiro [1.7K]

Answer:

  10/33

Step-by-step explanation:

The usual approach (if your calculator won't do this for you) is to convert the mixed number to an improper fraction, then perform the division. That division can be accomplished by multiplying the numerator by the inverse of the denominator.

  1 7/15 = (15+7)/15 = 22/15

Then ...

  (4/9)/(22/15) = (4/9)(15/22) = (2·2·3·5)/(3·3·2·11) = (2·5)/(3·11) = 10/33

_____

<em>Alternate solution</em>

Both fractions can be given the same denominator:

  4/9 = 20/45

  1 7/15 = 22/15 = 66/45

Now, the division is ...

  (20/45)/(66/45) = 20/66 = 10/33
