If the numerator of certain fraction is increased by 200% and the denominator is increased by 150% the new fraction is thus formed is 9/10 .

3 / 4

Hope this helps.  Plz mark brainliest.

Step-by-step explanation:

Let the original fraction be a / b.

a increased by 200%

= a + 200% of a

= a + 200% × a

= a + 2 × a

= 3a

b increased by 150%

= b + 150% of b

= b + 1.5 × b

= 2.5b

The new fraction is 3a / 2.5b

3a / 2.5b = 9 / 10

=> a / b = ( 9 × 2.5 ) / ( 3 × 10 )

= 22.5 / 30

= 45 / 60

= 3 / 4

answer:

I do not know haha

Define the fraction:

Numerator increased by 200% and denominator increased by 150%:

Find x

3x = 9

x = 9 ÷ 3

x = 3

Find y:

2.5y = 35

y = 35 ÷ 2.5

y = 14

Find the fraction:

ANSWER:

if we take numerator 3 and denominator 4 then

Step-by-step explanation:

3×200/4×350 = 600/1400

Let numerator be X

Denominator be Y

when numerator is increased by 200% , it becomes 2X+X

When denominator increased by 300% ,it becomes 3Y+Y

so from the question (2X+X)/(3Y+Y) =11/12

=> 3X/4Y = 11/12

=> X/Y = 44/36

=> X/Y = 11/9

Step-by-step explanation:

let the original fraction be x/y(1)

since numerator is increased by 200% the new numerator would be 2x

similarly denominator would be 3y

so new fraction would be

2x/3y=2

2x=6y

x=3y

now substituting value of x in (1) expression

x/y=3y/y

=3

Ans=3

original fraction is 1/4

answer:

step-by-step explanation:

no it's not correct.

=> x²-6x-7 = 0

=> x²+x-7x-7 = 0

=> x(x+1) - 7(x+1) = 0

=> (x+1) (x-7) = 0

=> x = -1 or x = 7
