The place values of decimals before the decimal point is one’s, ten’s, hundred’s, and thousands, etc. The place values after the decimal point starts with ten’s, hundreds and thousands, etc. Here, shall we study about 10.5 math answers in this article.


Example Problems for Math 10.5 Answers


Decimal 10.5 Using Addition Operation in Math:

Problem 1:

Add 4.4 and 6.1?

Solution:

Let us add the two decimals in the given problem and the result should be the sum of the two decimals.

4.4 (addend)

6.1 (addend)

-------------

10.5 (sum)

-------------

The sum for adding 4.4 and 6.1 is 10.5.

Decimal 10.5 Using Subtraction Operation in Math:

Subtract 43.8 and 33.3?

Solution:

Let us subtract the two decimals in the given problem and the result should be difference of the two decimals.

43.8 (minuend)

33.3 (subtrahend)

---------------

10.5 (difference)

---------------

The difference for subtracting 43.8 and 33.3 is 10.5.

Decimal 10.5 Using Multiplication Operation in Math:

Problem 3:

Multiply 21 and 0.5?

Solution:

Let us multiply the two decimals in the given problem and the result should be the product of the two decimals.

21 ×

0.5

-----------------

10.5

-----------------

The product of multiplying 21 and 0.5 is 10.5.

Decimals 10.5 Using Division Operation in Math:

Problem 4:

Multiply 9.45 and 0.9?

Solution:

Let us divide the two decimals in the given problem and the result should be the quotient of the two decimals.

0.9)9.45(

First we write the given decimals as by multiplying the decimals with 10 for dividend and divisor. Multiply the divisor 0.9 with 10 gives 9 and the dividend with 10 gives 94.5.

Let us continue with the division method.

9)94.5(1

9

-----------------

04

-----------------

The number 4 cannot go into 4. So, it can go into 45 for 5 times.

Number 9 go into 45 for 5 times.

9)94.5(105

9

--------------------

045

045

-------------------

0

--------------------

In the dividend, there is a decimal point after before one digit from the right hand side, so put the decimal point one digit before in the answer.

So, the quotient 105 should be 10.5.

The quotient for dividing 9.45 by 0.9 is 10.5.
