If you pay attention is just adds a ten and minuses a 1 from each number.
8,7,6,5. And 1,2,3,4.
Hope this helps :)
First, we have two multiply two fractions (7/16 x 4/3) which we do top x top and bottom x bottom which gives us 28/48
Second, we do 28/48 x 1/2 which is 28/96.
Lastly, we simplify 28/96 which gives us 7/24
It isn't because since 9 is the product of 3×3, you multiply the 6 by 3 as well, which makes 18.

The number of the board's price of $6.50 will be 12 and the number of the boards for the price of $9.50 will be 8.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
Given that:-
The total cost of 20 boards is $166. one size costs $6.50, and the second size costs $9.50.
Let the number of the boards for the price of $6.50 is x and for $9.50 is y. So the expression will be given as:-
6.50x + 9.5 y = 166
x + y = 20
Put x = 20 - y
6.50( 20 - y) + 9.5y = 166
130 - 6.50y + 9.50y = 166
3y = 166 -30
3y = 36
y = 12
Now the value of x will be:-
x = 20 - y = 20 - 12 = 8
Therefore the number of the board's price of $6.50 will be 12 and the number of the boards for the price of $9.50 will be 8.
