What number should be subtracted from [1\2-1/4]to get -1/5

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

$➩ \frac{1}{2} - \frac{1}{4} = \frac{2 - 1}{4} = \frac{1}{4}$

Let X be subtracted from 1/4 to get -1/5

$➩ \frac{1}{4} - x = \frac{ - 1}{5}$

$➩ - x = \frac{ - 1}{5} - \frac{1}{4}$

$➩ - x = \frac{ - 4 - 5}{20}$

$➩ - x = \frac{ - 9}{20}$

$➩x = \frac{9}{20 \: } \: answer$

Hope it helps you..!!!

Answer 2

Answer:

9/20

Step-by-step explanation:

so the equation formed is [1/2-1/4]-x=-1/5

we need to find the value of x in the above equation

lcm of 2 and 4 is 4

[(1×2/2×2)-1/4]- × = -1/5

[2/4-1/4]-x=-1/5

1/4-x=-1/5

then we transpose(interchange) -x and -1/5 so the minus sign becomes plus sign

1/4+1/5=x

lcm of 4 and 5 is 20

1×5/4×5 +1×4/5×4=x

5+4/20=x

9/20=x

so the number we should subtract to get -1/5 is 9/20

I hope this helps
