Write three numerical expressions that are equivalent to (0.0004) . (0.005)

The three equivalent numerical expressions are:

Solution:

We have to write three numerical expressions that are equivalent to (0.0004) . (0.005)

Given expression is:

(0.0004) . (0.005)

First numerical expression:

We know that 0.0004 can be written in fraction as:

Similarly,

Therefore,

Second numerical expression:

The first numerical expression can be simplified to get second numerical expression

Third numerical expression:

The given expression can be expressed in scientific notation:

Steps for converting to scientific notation:

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

Therefore, third equivalent numerical expression is:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

happy to

pls mark as brainliest

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
