Question

4. Simplify
c) 2 3/4 × 1/2 - 3/5​

Answer 1

Answer:

$\frac{31}{40}$

Step-by-step explanation:

$2 \frac{3}{4} \times \frac{1}{2} - \frac{3}{5} \\ \\ \implies \: \frac{11}{4} \times \frac{1}{2} - \frac{3}{5} \\ \\ \implies \: \frac{11}{8} - \frac{3}{5} \\ \\ \implies \: \frac{55 - 24}{40} \\ \\ \implies \: \frac{31}{40}$

Answer 2

Answer:

$\huge \: \frac{3}{4} \times \frac{1}{2} - \frac{3}{5} \\ \\ \\ \huge \frac{3}{6} - \frac{3}{5} \\ \\ \\ \huge = \frac{15 - 18}{30} \\ \\ \\ \huge = \frac{( - 3)}{30} \\ \\ \\ \huge = \frac {( - 1)}{10}$
