2.5 What is the difference between relational understanding and instrumental​

Mathematics
1 answer:
Afina-wow [57]2 years ago
3 0

Answer:

Instrumental understanding – having a mathematical rule and being able to apply and manipulate it. Relational understanding – having a mathematical rule, knowing how to use it AND knowing why it works.

Step-by-step explanation:

Instrumental understanding involves “memorising which problems a method works for and which not, and also learning a different method for each new class of problems” (Skemp 1987, p. 159), is a desire to know “some kind of rule for getting the answer” (p. 155) so that a student can “latch on it and ignore the rest”

I Need help plz help me i Sony understand

A. 2, 200, 2000  

This is multiplying the number by 10 each time. In other words, just adding an extra zero to the end of it. 

b. 340, 0.034 

This one is moving the decimal place forward two places. 10^-2, so removing two zeros from the end of it until eventually you reach decimals and have to move the decimal forward twice, which is essentially what you're doing here.

c. 85700, 857, 0.857

In this one, you remove one zero from the end. You move the decimal forward once when you reach the decimals. This would be 10^-1

d. 444000, 4440000, 44400000

In this one, you multiply each one by 10. Add on a zero to each one.

e. 0.095, 9500000, 950000000

You multiply this one by 10^2, so the number increases.

6(3-e) = 42<br> e =<br> what does e equal
Rainbow [258]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{e =  - 4}}}}}

Step-by-step explanation:

\sf{6(3 - e) = 42}

Distribute 6 through the parentheses

⇒\sf{18 - 6e = 42}

Move 18 to right hand side and change it's sign

⇒\sf{ - 6e = 42 - 18}

Subtract 18 from 42

⇒\sf{ - 6e =  24}

Divide both sides of the equation by -6

⇒\sf{ \frac{ - 6e}{ - 6}  =  \frac{24}{ - 6} }

Calculate

⇒\sf{e =  - 4}

Hope I helped!

Best regards!!
