Question

2/5+-11/15+4/5+-2/3 Simplify

Answer 1

Solution:

3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

= (3 × 3 + 1)/3 ÷ 5/3 – 1/10 of (2 × 2 + 1)/2 + 7/4

= 10/3 ÷ 5/3 - 1/10 of 5/2 + 7/4

                     [‘of’ simplified]

= 10/3 × 3/5 – ½ × ½ + 7/4                  [‘÷’ simplified]

= 2/1 - ¼ + 7/4                   [‘×’ simplified]

= (2 × 4)/1 × 4) - (1 × 1)/4 × 1) + (7 × 1)/4 × 1)

= 8/4 - ¼ + 7/4

[Now the denominators are same of all the fractions]

= (8 – 1 + 7)/4                  [‘+’ and ‘-‘ simplified]

= 14/4

= 7/2

Answer 2

Answer:

$= ( \frac{2}{5} - \frac{11}{15} ) + ( \frac{4}{5} - \frac{2}{3} ) \\ \\ = ( \frac{6 - 11}{15}) + ( \frac{12 - 10}{15} ) \\ \\ = \frac{ - 5}{15} + \frac{2}{15} \\ \\ = \frac{ - 3}{15} \\ \\ = - \frac{1}{5}$
