Asta made a fraction number line to help her multiply 3 x 4/5

1 answer:

7 0

3 times 4/5 can also be known as 3 times 4 over 5, which is 12 over 5.
12/5 can be simplified to 2 2/5 or 2.4. This is the answer to 3 * 4/5
And I have no idea how to draw a number line on a computer.

The expanded form for the number 165.038 is 100+60+5+0.03+0.008.

<h3>What is the expended form of decimal numbers?</h3>

Writing decimals in expanded form simply means writing each number according to its place value. This is done by multiplying each digit by its place value and adding them together. Let's look at an example: 2.435. In words, we would say this as two and four hundred thirty-five thousandths.

In the given question expended form 100+60+5+30+8 is wrong.

After decimal point the first digit is at the tenth place and second digit at the hundredth place and third is at the thousandth place and so on....

165.038 = 100+60+5+ $\frac{0}{10}$ + $\frac{3}{100}$ + $\frac{8}{1000}$
