You just multiply the numerator and denominators. For example:
2/4 x 3/5.
Multiply 1 and 3 for the numerator: 6
Multiply 4 and 5 for the denominator: 20
The answer is 6/20, or 3/10 simplified.

The question is not clearly stated, below is a possible match of the clearly and completely stated question:

Tony is writing a fraction equivalent to 2/7 using the formula 2*m/7*n. Which statement about m and n must be true so that tony fraction has the same value as 2/7

A. M/n has to be greater than 1

B. M/n has to equal 7

C. M/n has to be greater than 2

D. M/n has to equal 1

Answer:

m/n has to equal 1 (D)

Step-by-step explanation:

$original\ fraction = \frac{2}{7} \\equivalent\ fraaction = \frac{2\ \times\ m}{7\ \times\ n} \\equivalent\ fraction\ = \frac{2}{7} \times\ \frac{m}{n} \\$

since the target for the equaivalent fraction is the same as the equivalent fraction ( $\frac{2}{7}$ ), the value of $\frac{m}{n}$ must be equal to 1, so that the multiplication will be:

$\frac{2}{7} \times 1 = \frac{2}{7}$

astraxan [27]

Answer:

Step-by-step explanation:

-8-4v=40 add 8 to both sides

-4v=32 divide both sides by -4

v= -8

3v+2v=25

5v=25 divide both sides by 5

v=5

x/2 - 8 = -14 add 8 to both sides

x/2= - 6

-6 * 2= -12

check

-12/2-8=-14

-6-8=-14

-14= -14

-6+n/3= -3 add 6 to both sides

n/3=3

3*3=9

check

-6+9= -3

-3 = -3

The graph of a quadratic function f has zeros of -8 and 4 and a maximum at (-2,18). What is the value of a in the function’s equ

Harrizon [31]

<h3>Answer: C) -1/2</h3>

==================================

Work Shown:

We will use the general vertex form y = a(x-h)^2+k

(h,k) is the vertex, and the 'a' value stretches or compresses the graph vertically

(h,k) = (-2,18) since the highest point is at (-2,18)

Use either root -8 or 4 to plug into the equation as well. I'll use -8

The root -8 means the point (-8,0) is an x intercept.

----------------

Plug the values mentioned into the equation below. Then solve for 'a'.

y = a(x-h)^2+k

y = a(x-(-2))^2+18 ... plug in (h,k) = (-2,18)

y = a(x+2)^2+18

0 = a(-8+2)^2+18 ... plug in (x,y) = (-8,0)

0 = a(-6)^2+18

0 = a*36+18

0 = 36a+18

36a+18 = 0

36a = -18 ... subtract 18 from both sides

a = -18/36 .... divide both sides by 36

a = (-1*18)/(2*18)

---------------

Alternatively, you could use (x,y) = (4,0), instead of (x,y) = (-8,0), and you'll get the same 'a' value as well.
