Answer:

1 3/4 = 7/4 = 1.75

Step-by-step explanation:

The process to arrive to the solution is explained in the pictures below.

Tyler needed to convert the mixed fraction

2 1/2  = (4+1)/2 = 5/2

If we multiply by 2 numerator and denominator

5*2/2*2 = 10/4

We substract

10/4 - 3/4 = 7/4 = 1.75

Hannah estimated that a bottle could hold 2.2 liters. The actual volume of the bottle was 2 litters. What was the percent error
MrRa [10]

Answer:

I dont have a direct answer but i think i can help.

Step-by-step explanation:

For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.
