Question

3.24 divided by 7.2 how do I figure out the answer to this

Answer 1

Answer:

0.45.

Step-by-step explanation:

We are asked to divide 3.24 by 7.2

Write as a division problem:

$\frac{3.24}{7.2}$

To divide 3.24 by 7.2, we will remove the decimal.  

We can see that numerator has two digits after decimal and denominator has one digit after decimal, so we will multiply numerator and denominator by 100 to remove decimal as:

$\frac{3.24\times 100}{7.2\times 100}$

$\frac{324}{720}$

$\frac{36\times 9}{36\times 20}$

$\frac{9}{20}$

$0.45$

Therefore, our quotient would be 0.45.

Answer 2

You can think of multiplication “backwards.” To solve 4.5 ÷ 5, think: What number multiplied
by 5 will give me 4.5? Or, _____ × 5 = 4.5. The answer is 0.9.

Or, think of “bananas” divided among a group of people. The only thing is, this time
the “bananas” are tenths, hundredths, or thousandths! For example, 0.035 ÷ 5 is “35 thousandths divided by 5”. Replace the thousandths by bananas
for a moment: “35 bananas divided by 5... equals 7 bananas.” The answer to the original
problem is 7 thousandths, or 0.007. Another example: 0.12 ÷ 4 is “12 hundredths divided by 4”. This is essentially the division
problem “12 divided by 4”, however, in terms of hundredths. The answer is 3 hundredths or 0.03.or just do 3.24÷7.2 which equals 0.45
