Compare - 40% of a is equal to $300 and 30% of b is equal to $400

B is greater than A.

Step-by-step explanation:

We have been given that 40% of A is equal to $300 and 30% of B is equal to $400. We are asked to compare both quantities.

Let us find A and B using our given information.

Similarly, we will find B.

We know that smaller percent of big number is greater than bigger percent of a small number.

Therefore, B is greater than A.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
