Answer 1

Answer:

0.032

Step-by-step explanation:

0.08% of 40 is equivalent to multiplying them: 0.08% × 40.

0.07% of 40 = ? ... 0.09% of 40 = ? ... 1% of 40 = ?

Introduction:

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

0.08% = 0.08 'out of one hundred',

p% is read p 'percent',

0.08% = 0.08/100 = 0.08 ÷ 100.

Calculate percentage:

'Percentage' is obtained by multiplying 40 by 0.08%.

0.08% × 40 =

(0.08 ÷ 100) × 40 =

(0.08 × 40) ÷ 100 =

3.2 ÷ 100 =

0.032 ≈

0.03;

How do we check the result?

If 0.08% × 40 = 0.032 =>

Divide 0.032 by 40...

... And see if we get as a result: 0.08%.

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.

Calculate the percent value:

0.032 ÷ 40 =

0.0008 =

0.0008 × 100/100 =

(0.0008 × 100)/100 =

0.08/100 =

0.08%
