Andre drank 1.5 liters of water he brought. If he drank 80% of his entire hike, how much did he drink?

Answers

Answer:

about 1.25

Step-by-step explanation:

Andre drank 1.2 liters out of 1.5 liters of water.

What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Andre who drank 1.5 liters of water he brought. He drank 80% of his entire hike.

Assume that he drank [x] liters of water. Then -

x = 80% of 1.5 liters

x = (80/100) x 1.5

x = 8/10 x 1.5

x = 1.2 liters

Therefore, Andre drank 1.2 liters out of 1.5 liters of water.
