Mac earned PHP 4,500 and Chiz earned PHP 5,400 last month. What is the ratio of their earnings?

To determine the ratio of Mac's earnings to Chiz's earnings, you start by identifying their individual amounts. Mac earned PHP 4,500, and Chiz earned PHP 5,400. The ratio is calculated as Mac's earnings divided by Chiz's earnings.

So, you express this as follows:

1. Write the ratio: ( \frac{Mac's earnings}{Chiz's earnings} = \frac{4500}{5400} ).

2. To simplify this ratio, divide both the numerator and denominator by their greatest common divisor (GCD), which in this case is 900.

3. Performing the division gives you ( \frac{4500 \div 900}{5400 \div 900} = \frac{5}{6} ).

This simplified ratio of 5:6 accurately represents the earnings of Mac and Chiz. It indicates that for every 5 parts of earnings Mac has, Chiz has 6 parts. This proportional relationship is essential when comparing the two amounts, allowing for a clear understanding of how their earnings relate to one another.
