Question

simplify
(2/7 x 7/5)-(9/5 x -10/9)-(3/2 x 100/5) in step by step​

Answer 1

$( \frac{2}{7} \times \frac{7}{5} ) - ( \frac{9}{5} \times (- \frac{10}{9}) ) - ( \frac{3}{2} \times \frac{100}{5} ) \\ = ( \frac{2}{5} ) - ( - 2) - (30) \\ = \frac{2}{5} - 28 \\ = \frac{2 - 140}{5} \\ = \frac{ - 138}{5} \\ = - 27 \frac{3}{5}$

Answer 2

Answer:

Right answer is 1540

and also this one is right answer >>>> -27.61

Step-by-step explanation:

(14×35) - (-90×45) - (300×10)

490 + 4050 - 3000

4540 - 3000

1540.

(0.28 × 1.4) - [1.8 × (-1.11)] - (1.5 × 20)

(0.392) - (-1.998) - (30)

0.392 + 1.998 - 30

2.39 - 30

-27.61
