Question

Evaluvate (3/7*-2/7)+(7/9*3/7)-(3/7*-4/5)​

Answer 1

Answer:

answer is 407/735

Step-by-step explanation:

(3/7 × -2/7) + (7/9 × 3/7) - (3/7 × -4/5)

3/7 × (-2/7 + 7/9 - [-4/5])

3/7 × (-2/7 + 7/9 + 4/5)

3/7 × ([-90 + 245 + 252]/315)

3/7 × (407/315)

1/7 × 407/105

407/735

Answer 2

Answer:

=(3/7*-2/7)+(7/9*3/7)-(3/7*-4/5)

=(0.43*-0.29)+(0.78*0.43)-(0.43*-0.4)

=(-0.1247)+(0.3354)-(0.172)

=-0.1247+0.3354-0.172

=0.2107-0.172

=0.0387
