Question

помогите решить очень нужно срочно!!! 1/4 + (0,3*1,2) - 4 целых 1/3 * 2/13=

Answer 1

1)0,3×1,2=0,36=36/100

2)
$\frac{1}{4} + \frac{36}{100} = \frac{25}{100} + \frac{36}{100} = \frac{61}{100}$
3)
$4 \frac{1}{3} \times \frac{2}{13} = \frac{13}{3} \times \frac{2}{13} = \frac{2}{3}$
$\frac{61}{100} - \frac{2}{3} = \frac{61 \times 3}{300} - \frac{2 \times 100}{300} = \\ = \frac{183}{300} - \frac{200}{300} = - \frac{17}{300}$
