Question

what should be subtracted from 3/11 to get 7/4​

Answer 1

Answer:

∴ x = - 65/44

Step-by-step explanation:

or, 3/11 - x = 7/4

or, -x = 7/4 - 3/11

or, -x = (7×11/4×11) - (3×4/11×4)

or, -x = 77/44 - 12/44

or, -x = (77-12)/44

or, -x = 65/44

∴ x = - 65/44

Answer 2

$let \: the \: numer \: be = \: \: \: \: x \\ from \: the \: question \\ \frac{3}{11} - x = \frac{7}{4} \\ \\ \frac{3}{11} - \frac{7}{4} = x \\ \\ \frac{(4 \times 3) - (7 \times 11)}{44} = x \\ \\ \frac{12 - 77}{44} = x \\ x = \frac{ - 65}{44}$
