Answer:

B. 60%

Step-by-step explanation:

24:40

6:10

60:100 = 60/100 or 60%

Answer:

B.60%

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

60% = 60 'out of one hundred',

p% is read p 'percent',

60% = 60/100 = 60 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 40 by 60%

60% of 40 is equivalent to multiplying them:

60% × 40 = ?

60% × 40 =

(60 ÷ 100) × 40 =

(60 × 40) ÷ 100 =

2,400 ÷ 100 =24

Proof

How do we check the result?

If 60% × 40 = 24 =>

Divide 24 by 40...

... And see if we get as a result: 60%

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

n/100 = n%, any number.
