"What do I want to find out?" is the first step.
1/3 + 2/5 • 2/3
2 • 2 = 4
5 • 3 = 15
1/3 = 5/15
5/15 + 4/15 = 9/15 = 3/5
1/3 + 2/5 • 2/3 = 3/5
If you would like to know what is the length of the painting, you can calculate this using the following steps:
an area = width * length
320 = 16 * length
length = 320 / 16
length = 20 inches
The correct result would be 20 inches.
Product means multiplication. So the equation would be xy ≤ 4.
