14.5% = 0.145

Step-by-step explanation:

The term 'percent' (%) actually means per 100. So when you say 14.5% it means 14.5 per 100. So when you put that into an equation it actually means:

A recipe for bran muffins calls for 2 1/2 cups of bran flakes. The recipe yields 9 muffins. How much bran flakes should be used
kolbaska11 [484]

10/3 bran flakes can make a dozen muffins

A recipe requires 2 1/2 cups of bran flakes

The recipe can make 9 muffins

Let's calculate the amount of bran flakes it will take to make 1 muffin

5/2 = 9

x= 1

cross multiply

9x= 5/2

x= 5/18

A dozen is 12, the number of bran flakes to make a dozen can be calculated as follows

5/18= 1

y= 12

cross multiply

y= 5/18 × 12

y= 10/3

Hence it will take 10/3 to make a dozen muffins

worty [1.4K]

Answer:

250 coches

Step-by-step explanation:

Proporción de empleados que vienen a trabajar con sus coches = 5/16

Número total de empleados = 800

Por lo tanto, número total de automóviles esperado = proporción de empleados que vienen a trabajar con automóviles * número total de empleados

 número total de coches esperados = 5/16 * 800

 número total de coches esperados = 250 coches
