NEEDED BY TOMORROW!
marissa [1.9K]

Answer:

0.375, Terminating

Step-by-step explanation:

Mackenzie has 32 books and 12 of which are by her favorite author.

One of the easier ways to convert something to a decimal is to first start as a fraction. We need to have it be the number of books by her favorite author (12) out of the total number of books that she owns (32)

This in the form of a fraction would be \frac{12}{32}

Now, let us reduce this fraction.

Both terms can be divided by 4

\frac{12}{32}/\frac{4}{4} \\\\\frac{3}{8}

Recall that \frac{1}{8} =0.125

This means that

\frac{3}{8} =3*0.125=0.375

As you can see. this decimal stops after 3 places, which means that it is terminating.

Could someone help I’m so confused
oksano4ka [1.4K]

Answer:

6/4

Step-by-step explanation:

ratio of x to y is the slope so

you can use butterfly method/cross multiply (multiply numerator on one side to the denominator on the other to bring all the terms up and then solve for y)

4(y+3)=6(x+2)

4y+12=6x+12

y=6/4x

so it would be 6/4
