What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total number of counters = 400

The number of counters that are red = 3/8 of total number of counters

= ( 3/8 ) x 400

= 3 x 50

= 150 counters

The number of counters that are yellow = 82 counters

So , the number of counters that are green =
Total number of counters - number of counters that are red - number of counters that are yellow

The number of counters that are green = 400 - 150 - 82

= 168 counters

Now , the percentage of counters that are green =
( number of counters that are green / total number of counters ) x 100

The percentage of counters that are green = ( 168 / 400 ) x 100

= 168 / 4

= 42 %

Hence , the number of counters that are green is 168 and the percentage of counters that are green is 42 %
