Question

What should be subtracted from 7/4
to get-2?​

Answer 1

Answer:

Hi here's your answer

Step-by-step explanation:

let the number which should be subtracted = x then,

$\frac{7}{4} - x = - 2$

$\frac{7}{4} = -2 + x$

$\frac{7}{4}+2 = x$

LCM = 4 so,

$\frac{7 + 8}{4} =x$

$\frac{15}{4} = x$

Therefore $\frac{15}{4}$ must be subtracted from $\frac{7}{4}$ to get - 2

Answer 2

Answer:

let the no. be x

then

=> 7/4-x= -2

=> 7-4x/4= -2

=> 7-4x = -2*4

=> 7-4x = -8

=> -4x = -8-7

=> -4x = -15

=> x = -15/-4

=> x = 15/4
