310 - 220 = 90
90/310 = x/100 (cross multiplication)
9000 = 310x
9000/310 = x
x = around 29%
Answer:
Step-by-step explanation:
In simpler words mathematics is the study of numbers , quantities, or shapes.
It is the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects.

Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports...
basically have to find the lowest common multiply of 6 and 9.
The LCM of 6 minutes and 9 minutes = 18 minutes
so if they both leave at 4:00 p.m., they would then both leave at 4:18 p.m.
7 because 13-6 is equal to 7
If < means less than than ≤ means less than or equal to
