Answer 1

Respuesta:

Explicación paso a paso:

1) 4/3 × 2/7

= 8 /21 x

2) (-7/9) × 9/5

= −7 /5

3) (-7/4) × 3/4 × (8/9)

= −21 /4 /4 ( 8 /9 )

= −21 /16 ( 8 /9 )

= −7 /6

4) 2/7 ÷ 5/3

= 2 /35 /3

= 2 /105

5) 8/9 ÷ (-3/4)

= 8 /9 −3 /4

=( 8 /9 )( 4 /−3 )

= (8)(4) /(9)(−3)

= −32 /27

6) {3/5 × [¬1/3]} ÷2/7

= −1 /5 /2 /7

= −1 /10 /7

= −1 /70

7) {8/9 × 5/9} ÷ {3/7 × 5/9}

= 40 /9 /9 /3 /7 (5) 9

= 40 /81 /3 /7 (5) 9

= 40 /81 /15 /7 /9

= 40 /81 /5 /21

= 56 /27

8) 1/9. (3/3).(5/4).(-3/7) ÷ 8/9

= −5 /6048

9) 12/5. 8/9 ÷ 3/11. 1/9

= 32 /495 /9

= 32 /4455

10) 2/9 ÷ 3/4 ÷ 5/7 ÷ 3/8

= 1 /1890 /3 /8

= 1 /5670 /8

= 1 /45360
