Answer:

1/3

Step-by-step explanation:

We have to make the denominator of all fractions to be 15:

Multiply both the 4 and the 5 in 4/5 by 3 to get 12/15.

Nothing has to be done to 3/15.

Next, multiply both the -2 and the 3 in -2/3 by 5 to get -10/15.

Solve:

12/15 + 3/15 - 10/15 = 5/15.

5/15 further simplifies to 1/3.

The final answer is 1/3.

allsm [11]

Given :

She run 3 miles 1 st day .

She run 5 miles 2 nd day .

Then she runs 7 miles per day .

To Find :

If she total runs 99 miles , for how many days has Carla been running 7 miles.

Solution :

The relation between total miles run and number of days she run 7 miles is :

$D=7n+3+5$

Putting , D = 99 miles , we get :

$7n+8=99\\\\n=\dfrac{91}{7}\\\\n=13$

1. 1/2 x4

Leviafan [203]

Answer:

Question one: 2
Question two: 3

Step-by-step explanation:

Given the following questions:

$\frac{1}{2} \times4$
$\frac{3}{4} \times4$

In order to find the answers, we need to remember that every integer has an invisible denominator of one. Then we simply multiply the numerators by the numerators and the denominators by the denominators.

Question one:
 $\frac{1}{2} \times4$
$4=\frac{4}{1}$
$\frac{1}{2} \times\frac{4}{1}$
$1\times4=4$
$2\times1=2$
$=\frac{4}{2}$

Simplify by reducing:
$\frac{4}{2}$
$\frac{4}{2} \div2=\frac{2}{1} =2$
$=2$

Question two:
 $\frac{3}{4}\times4$
$4=\frac{4}{1}$
$\frac{3}{4} \times\frac{4}{1}$
$3\times4=12$
$4\times1=4$
$=\frac{12}{4}$

Simplify by reducing:
$\frac{12}{4}$
$=\frac{12}{4}\div4=\frac{3}{1} =3$

Your answers are "2 and 3."

Hope this helps.
