15.5 * 28/112 + 1230 + 240 = x/5
15.5 * 0.25(28 / 112) + 1230 + 240 = x/5
3.875(15.5 * 0.25) + 1470(1230 + 240) = x/5
1473.875(3.875 +1 470) = x/5
1473.875 * 5 = x(as 5 moved from rhs to lhs it changes is symbol)
therefore answer is 7369.375

Solving Arithmetic Problems

Problem 1: 15.5×28÷112

To solve this arithmetic problem, we need to follow the order of operations, which is commonly known as PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction). In this case, we have only multiplication and division operations. So we need to perform them from left to right.

First, we will perform the multiplication operation: 15.5×28 = 434

Next, we will perform the division operation: 434÷112 = 3.875

Therefore, the solution to the problem 15.5×28÷112 is 3.875.

Problem 2: 1230÷240=?

To solve this arithmetic problem, we need to again follow the order of operations, which is PEMDAS. In this case, we have only a division operation.

We can solve this problem by performing long division. Here's how to do it:

240)1230(5
1200
------
30

Therefore, the solution to the problem 1230÷240 is 5.

Problem 3: 5?
