Question

If the difference in the amount of rice ordered is 45kg, write down an equation. A) x+y=45

B) x=y+45
C) x−y=45
D) x⋅y=45

Answer 1

To find the equation representing a difference of 45kg between two amounts of rice, we use the equation x - y = 45, signifying that x is 45kg more than y. The correct equation would be x - y = 45.

Step-by-step explanation:

The question is asking for an equation that represents the situation where the difference in the amount of rice ordered is 45kg. To signify a difference, we would subtract one quantity from another. Therefore, the correct equation would be x - y = 45. This equation shows that when you take the amount of rice represented by variable y away from the amount represented by variable x, the difference should be 45kg.

Percentage difference tells us the measurement of two different experimental values where one value is higher than the other value. In other words, the percentage difference is defined as the absolute value of the ratio of the difference between two numbers and their average, expressed as a percentage.

For example, if we need to find out the percentage of customers in April over the customers in May, the percent difference formula will be used. Let us look at the percent difference between two numbers and the steps to calculate the same.
