100 POINTS 100 PUNTOS

If I buy an apple with 100 coins, how many coins do I need to have 1000 apples?

Si compro una manzana con 100 monedas, ¿cuántas monedas necesito para tener 1000 manzanas?

10,000 coins

Step-by-step explanation:

We can use a ratio to solve

1 apple        100 apples

  =

100 coins        x coins

Using cross products

1x = 100 * 100

1x = 10,000

We need 10,000 coins

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
