The denominator of a fraction is 4 more than the numerator if both are decreased by 3 the simplified result is 6/7 find original

Hitman42 [59]

<u>Answer:</u>

The denominator of a fraction is 4 more than the numerator. The original fraction is $\frac{27}{31}$

<u>Solution:</u>

Given that

Denominator of fraction is 4 more than the numerator.

Let’s say numerator of fraction be represented by variable x.

So denominator of a faction as it is four more that numerator will be x + 4

Also given if both decreased by three than simplified result is $\frac{6}{7}$

$=>\frac{(x-3)}{((x+4)-3)}=\frac{6}{7}$

Solving above equation for x

=> 7(x – 3 ) = 6 ( x + 1 )

=> 7x – 21 = 6x + 6

=> 7x – 6x = 6 + 21

=> x = 27

Numerator of fraction = x = 27

Denominator of fraction = x + 4 = 27 + 4 = 31

$\text {required fraction}=\frac{\text {numerator}}{\text {denominator}}$

$= \frac{27}{31}$

Hence the original fraction is $\frac{27}{31}$

Solve X/3 - 2X+1/3 = X-3/5

iren2701 [21]

Answer:

Answer is 3

Step-by-step explanation:

x/3-2x/1+3 =x-3/5

x/3-x/3 = x-3/5

0=x-3/5

0=x-3

3=x

sothat, x = 3 ans

Draw the triangle with the given vertices. Multiply each coordinate of the

allochka39001 [22]

Answer:

The two triangles would be similar.

Step-by-step explanation:

Since, when each coordinate of the vertices of a triangle is multiplied by a number k,

Then the triangle is dilated by the factor k,

i.e, the resultant triangle is similar to the triangle.

1. Given vertices of the triangle,

(0, 0), (1, 3) and (2, 1)

By multiplying each coordinate of the vertices by 3,

We obtain the triangle having vertices,

(0, 0), (3, 9), (6, 3)

draw the points in coordinates plan and join them by straight line,

We observed that triangles are similar.

2. Given vertices of the triangle,

(-3, -2), (-1, 4) and (2, - 2)

By multiplying each coordinate of the vertices by 3,

We obtain the triangle having vertices,

(-9, -6), (-3, 12) and (6, - 6)

Draw the points in coordinates plan and join them by straight line,

We observed that triangles are similar.
