Question

Write the following in decimal form:
\[\left( {5 \times 10} \right) + \left( {6 \times 1} \right)\]

Answer 1

Hint:
We will solve the expression using the rule of BODMAS. We will solve the brackets first. We will add the numbers obtained upon solving the brackets. Then we will write the solution in decimal form.

Complete step by step solution:
We will solve the brackets first in accordance with the BODMAS rule. We will solve the left-most bracket first.
We know that 5 times 10 is 50.
\[\left( {5 \times 10} \right) = 50\]
We will solve the right-most bracket:
We know that 6 times 1 is 6. So,
\[\left( {6 \times 1} \right) = 6\]
We can see that there’s a plus sign between the 2 brackets. So, we will add the results obtained from solving the brackets in the expression.
Adding the two numbers, we get
\[50 + 6 = 56\]
We will express the result in decimal form. We know that the decimal form is used to represent the fractional and whole part of a number. The symbol of a decimal is a point or a dot. All the digits to the right of the decimal point represent the fractional part of the number and all the digits to the left side of the decimal point represent the whole part of the number.
We can see that 56 does not have any fractional part.

So, 56 will be written as \[56.0\] in decimal form. The 0 to right of the decimal point indicates that 56 does not have any fractional portion.

Note:
Any number can be represented in decimal form. We do not need to write whole numbers in decimal form because it is already implied. For example, 34.00 can simply be written as 34.
Here we have used the BODMAS Rule. We know that according to the BODMAS Rule, in a mathematical expression we should apply the mathematical operations in a certain order which is given by the letters BODMAS:
B-Brackets
O-Of
D-Division
M-Multiplication
A-Addition
S-Subtraction
