Question

Subtract :-

$1. \: \sf \bigg(\frac{ - 11}{4} - \frac{11}{2} \bigg)$
$2. \: \sf \bigg( \frac{ - 11}{4} - 0 \bigg)$
​

Answer 1

Explanation:

Given:

$\begin{gathered}1. \: \sf \bigg(\frac{ - 11}{4} - \frac{11}{2} \bigg) \\ \end{gathered}$

$\begin{gathered}2. \: \sf \bigg( \frac{ - 11}{4} - 0 \bigg) \\ \end{gathered}$

To find: Subtraction

Solution:

$\begin{gathered}1. \: \sf \bigg(\frac{ - 11}{4} - \frac{11}{2} \bigg) \\ \end{gathered}$

Step 1:Take LCM

LCM(2,4)=4

Step 2: Solve

$= \frac{ - 11\times 1 - 11 \times 2}{4} \\ \\ = \frac{ - 11 - 22}{4} \\ \\ = \frac{ - 33}{4}$

$\begin{gathered}2. \: \sf \bigg( \frac{ - 11}{4} - 0 \bigg) \\ \end{gathered}$

Sol: As subtraction of zero do not change the number.

So, it's answer is -11/4

Or

$= \frac{ - 11}{4} - \frac{0}{1} \\ \\ = \frac{ - 11 - 0 \times 4}{4} \\ \\ = \frac{ - 11 - 0}{4} \\ \\ = \frac{ - 11}{4}$

Final answer:

$\begin{gathered}1. \: \sf \bigg(\frac{ - 11}{4} - \frac{11}{2} \bigg)=\frac{-33}{4} \\ \end{gathered}$

$\begin{gathered}2. \: \sf \bigg( \frac{ - 11}{4} - 0 \bigg)=\frac{-11}{4} \\ \end{gathered}$

Hope it helps you.
