Explain why it is important to line up decimal points when you are adding and subtracting decimals. Use the problem 6.32 – 0.5 i
Mazyrski [523]

Answer:

Kindly check explanation

Step-by-step explanation:

When performing addition and subtraction of decimals, it is important to arrange the numbers being added or subtracted such that the decimal points are in line. This is particularly important so that the place value of the numbers are in accord.

To simplify, when then decimals are in line, then the tenth value of the first number will be added to the tenth value of the second. Without this arrangement, one might be adding the hundredth placed value to the tenth or unit value which is mathematically incorrect and will yield a wrong result.

For instance :

6.32 - 0.5

Here, when the decimal point of each number is in line, the tenth placed value of the first number (3) matches the tenth placed number of the second number (5) and all others also fall in place automatically.

____6.32

- ___0.5

________

___ 5.82

Please help me.........
Dafna1 [17]

Answer:

Option D

Step-by-step explanation:

From the spinner we see there are 5 colours in there.

These are;

Green, Yellow, Red, Purple, Blue.

This means that when it is spinned, there's possibility of getting only one colour per spin.

Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.

This means, all possible outcomes will be 5 × 2 = 10 outcomes.

With each colour possibly showing up with either tail or head.

Correct answer is Option D as it has 10 possible outcomes in the correct order.
