Answer:

1/2 ornament in an hour

Step-by-step explanation:

Given

$Orna\ ments = 2$

$Time = 4$

Required

Determine the ornaments per hour

This question implies that we calculate the unit rate.

$Unit\ Rate = \frac{Orna\ ments}{Time}$

Substitute values for Time and number of ornaments

$Unit\ Rate = \frac{2}{4}$

$Unit\ Rate = \frac{1}{2}$

<em>This implies that Constance can decorate 1/2 ornaments in an hour</em>

How to improve in math?

Arte-miy333 [17]

The best way is to do problems over and over again and making mistakes with them.There is no point in doing them if you get correct answers.
When you make mistakes you ask someone what’s wrong and try not to make that mistake again.
That’s how I became a master at maths and physics.

As for help with calculus the important thing is to understand how graphing works.
Once you got that do more questions.
So basically to summarise make mistakes don’t repeat and find out how it works

Hope this helps:)
