You and your friend each have a canvas of the same size. You divide your canvas into 5 sections and paint 3 of them. Your friend divides her canvas into 7 sections and paints 4 of them. Who paints more?

Answers

The one one paints 3/5, you would find a common denominator and it would be 21/35 and 20/35 so “you”

The person who paints more is given by the inequality equation 3/5 >  4/7

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the number of canvas be 35 ( LCM of 5 and 7 )

Now , when you divide 35 into 5 sections and paints 3 of them ,

The fraction A = 3/5

And , when your friend divide 35 into 7 sections and paints 4 of them

The fraction B = 4/7

And , the inequality equation is A > B

Substituting the values in the equation , we get

3/5 > 4/7

Hence , the one who paints more is you with 3/5 of the canvas
