4/5 times 9/2
Multiply eg: 4(3+2)=20
8 divided by 2 = 4, multiply 4 by 7 = 28, subtract 4 from that = 24.
It is 14/(3+4) = 2

"9 divided by 3" and "2 divided by 4" can be evaluated simultaneously.
To solve this expression, you need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). In this case, you first perform the division 16 divided by 4 to get 4. Then, you multiply 4 by 2 to get the final answer of 8.
In equivalent division, you multiply (or divide) the dividend and the divisor by the same number to form a new problem that is easier to calculate metally. The new problem will produce the same quotient. ie: 2 divided by 1/2, if you multiply 2 by 2 you get 4 and if you multiply 1/2 by 2 you get 1. 4 divided by 1 = 4. This is the same as the answer to 2 divided by 1/2 (4), it is just easier to do in your head.
Multiply eg: 4(3+2)=20
Well, its simple really. The expression for triangular is n(n+1) over 2 (divided by 2). You would then plug in the number 4 (because of 4th triangular). The equation would now be 4(4+1) over 2. Now you would do the parentheses making the problem 4(5) (4 times five) over 2. Than you would multiply 4 and 5 now making your problem 20 over 2 (or 20 divided by 2). 20 divided by 2 equals 10 making the final answer 10.
The expression is: v/4
8 divided by 2 = 4, multiply 4 by 7 = 28, subtract 4 from that = 24.
It is 14/(3+4) = 2
14/(3 + 4) = 2
