Question

a)(-3/4)-(-1/3)+(-2/5)​

Answer 1

a)

$( - \frac{3}{4} ) - ( - \frac{1}{3} ) + ( - \frac{2}{5} )$

$- \frac{3}{4} + \frac{1}{3} - \frac{2}{5}$

4, 3, 5 | 2

2, 3, 5 | 2

1, 3, 5 | 3

1, 1, 5 | 5

1, 1, 1 | 1

MMC = 2 . 2 . 3 . 5 = 60

$\frac{ - 45 + 20 - 24}{60}$

$\frac{ - 49}{60}$

$- \frac{49}{60} = - 0.816$
