## Faman39 Group Title Two lines are related by the scale 4 centimeters5 decimeters. How many times larger is the larger line? 1.25 12.5 125 1,250 one year ago one year ago

1. LukeBlueFive Group Title

1 decimeter = 10 centimeters So: 5 decimeters = 50 centimeters

2. Faman39 Group Title

So how will i do this?

3. LukeBlueFive Group Title

To find the ratio of how much longer something is than something else, you divide it. For example: $\frac{100ft}{10ft} = 10$ Which means that something 100 feet long is 10 times longer than something 10 feet long.

4. Faman39 Group Title

Are we have to divide 4/5

5. LukeBlueFive Group Title

Well, you can only divide values with like terms, and centimeters ≠ decimeters. Also, to avoid confusion, put the larger number on top when dividing.

6. Faman39 Group Title

got 1

7. LukeBlueFive Group Title

8. Faman39 Group Title

no you told to divide 5/4

9. Faman39 Group Title

isnt tht u mean ?

10. LukeBlueFive Group Title

Well, if you divide: $\frac{5 decimeters}{4centimeters}$ You'll get the ratio of 5 decimeters to 4 centimeters, which isn't what the problem's asking for. It wants to know their relative distances, so you need to change 5 decimeters into the equivalent number of centimeters, using the following equation: $x centimeters = 10xdecimeters$ Or, in other words, there are 10 centimeters in every decimeter.

11. LukeBlueFive Group Title

Sorry, the equation is actually: $centimeters = 10x decimeters$ Where x is the number of decimeters

12. Faman39 Group Title

40?

13. Faman39 Group Title

50 /40 1. 25

14. LukeBlueFive Group Title

Close. Leave the bottom number as 4, since it's already in centimeters.

15. Faman39 Group Title

12.5, thank you sooooooooooooooooooooo much!!!!!!!!! your terrifically great!!!!!!!!!!!!!

16. LukeBlueFive Group Title

No problem, just glad it all worked out in the end.

17. Faman39 Group Title
