Leanne is not correct as she does not multiplied 8 times 4.3 correctly.
Further explanation:
Given:
It is given that Leanne multiplied 8 times 4.3 and she got 32.24.
Calculation:
[tex]\boxed{\text{Multiplication}}[/tex] is a mathematical operation such that two real numbers are performed in such a way that they derive a third number called product. The sign used for multiplying two numbers is [tex]\times\text{ and }\cdot[/tex].
For example:
Suppose there are two numbers 5 and 10. Now multiply both the numbers as,
[tex]5\times10=50[/tex]
Therefore, 50 is the product of 5 and 10.
There are two numbers with decimal 5.5 and 8. Now, multiply both the number as,
[tex]5.5\times8=44[/tex]
Here we will not multiply each of the number 5.5 and 8 separately as shown,
[tex]5.5\times8\ne40.40[/tex]
The above method is not a correct way of multiplication.
As Leanne multiplied 8 times 4.3, it means she multiplied the number 4.3 eight times. Hence, Leanne is not correct.
The correct method to multiply 4.3 eight times is,
[tex]\begin{aligned}(4.3)\times(4.3)\times(4.3)\times(4.3)\times(4.3)\times(4.3)\times(4.3)\times(4.3)&=(4.3)^{8}\\&=116882.002\end{aligned}[/tex]
The value after multiplying 8 times 4.3 is 116882.002.
This means Leanne is not correct as she does not multiplied 8 times 4.3 correctly.
