Answer 2

Respuesta:

Explicación paso a paso:

30% de 30

= ( 30 / 100 ) x 30

= ( 30 x 30 ) / 100

= 3 x 3

= 9

20% de 50

= ( 20 / 100 ) x 50

= ( 20 x 50 ) / 100

= 2 x 5

= 10

80% de 700

= ( 80 / 100 ) x 700

= ( 80 x 700 ) / 100

= 80 x 7

= 560

75% de 250

= ( 75 / 100 ) x 250

= ( 75 x 250 ) / 100

= 75 x 25 / 10

= 75 x 5 / 2

= 375 / 2

= 187,5

65% de 100

= ( 65 / 100 ) x 100

= ( 65 x 100 ) / 100

= 65

35% de 84

= ( 35 / 100 ) x 84

= ( 7 / 20 ) x 84

= ( 7 x 84 ) / 20

= ( 7 x 21 ) / 5

= 147 / 5

= 29,4

25% de 90

= ( 25 / 100 ) x 90

= 90 / 4

= 22,5

90% de 20

= ( 90 / 100 ) x 20

= ( 90 x 20 ) / 100

= 9 x 2

= 18

85% de 150

= ( 85 / 100 ) x 150

= ( 85 x 150 ) / 100

= 85 x 15 / 10

= 85 x 3 / 2

= 255 / 2

= 127,5
