Most people will see a much smaller Mastery percentage change. With this specific course update, we expect that Mastery percentages will change by a maximum of 61%. This change would change your Mastery percentage from 90% to 82%. For example, if you mastered 90 out of 100 skills in a course, and we added 10 new skills, your mastery skill count would then be 90 out of 110. When we add new content and remove old content, Mastery percentages often change because the number of available skills changes. One consequence of adding this new content is that it may impact learners’ Mastery percentages. And there you have it, we've expressed it as both a fraction and a decimal.We are excited to share that we've made significant enhancements to our Pre-Algebra. That, not just one hundredth, but two hundredths, so it would be three, two tenths, and then two hundredths. Three and two tenths, and so I'm starting here at 3.2. Now another way that youĬould've approached it is hey, I'm starting at 3.2 or Is three and 22 hundredths, 22 hundredths, and ofĬourse, you could also write that as a mixed number. And you could view three and three tenths as three and 30 hundredths. It, you could view 3.2 or three and two tenths as So this is between three and two tenths and three and three tenths. We're between three and two tenths and three and three tenths. All right, so here, our point, it's not between two whole numbers. Let's see how you can, if you can identify how it is different andĪnswer the question. So here, we're once again asked to express the point on the number line as both a fraction and a decimal, but this one's a little bit different. Then in the tenths place, well we have two tenths. Write that as a decimal, that would be four, and If we wanted to write it as a fraction or as a mixed number, this would be four and two tenths. Is four and one tenth, and now this is four right Two, three, four, five, six, seven, eight, And the space between four and five is divided into one, So we can see that the point in question, it's at a higher value thanįour and it's less than five. So pause this video and have a go at that. Told express the point on the number line as bothĪ fraction and a decimal.
