Question

Simplify: 1/3×−5/7×−21

​

Answer 1

Answer:

Answer:

35 / 42

Step-by-step explanation:

3 / 7

= ( 3 × 6 ) / ( 7 × 6 )

= 18 / 42

5 / 14

= ( 5 × 3 ) / ( 14 × 3 )

= 15 / 42

1 / 21

= ( 1 × 2 ) / ( 21 × 2 )

= 2 / 42

( 5 / 14 ) + ( 3 / 7 ) + ( 1 / 21 )

= ( 15 / 42 ) + ( 18 / 42 ) + ( 2 / 42 )

= ( 15 + 18 + 2 ) / 42

= 35 / 42
