Question

Brittany is making a model boat and needs 4 pieces of string to rig the sails. Each piece of string needs to be 4/5 foot. She decides to cut the 4 pieces from a longer piece of string that is 15.2 feet in length.

How much string will remain after Brittany cuts the 4 pieces of string?

Answer 1

A. 5 feet
B. 12 feet
C. 18.4 feet
D. 10.4 feet

Answer 2

This is just like the previous problem. Calculate how much Brittany is going to use 4 pieces each 4/5 ft long or a total of 16/5 ft or 3 1/5 feet or 5.2 feet.
The piece that this is going to be removed from is 15.2 feet since this is in decimal units use the 5.2 feet
15.2-5.2 = 10 ft. I don't see this as a choice have you copied the choices correctly or I have goofed both are possibilities! lol

Answer 3

radar, I think your conversion from 3 1/5 to 5.2 feet is perhaps incorrect?

Answer 4

I see my error it is 3.2 that i subtrtace from the 15.2 or 12 feet

Answer 5

Yes joshusnoble2000 therein is the problem, I had a "senior" moment lol

Answer 6

Haha. It happens to the young too. Embarrassingly often for this one.

Answer 7

Yes indeed, I hope Kyrie is not ruined for life because of that mistake. How about Kyrie did you see where I goofed?

Answer 8

3 1/5 =3.2 NOT 5.2 lol

Answer 9

Lol you didn't ruin me. But lost me...Yes.

Answer 10

Lol I have no idea what the answer might be! D:

Answer 11

Where are you at with this. Do you see how the amount used by brittany (total) is 3.2 ft.

Answer 12

The answer is 12, but I want you to understand how to solve it. The first step it figure out how much Brittany used.

Answer 13

is the answer C?

Answer 14

No it is B

Answer 15

:O well darn..I still don't understand this! :'S

Answer 16

Choice C of 18.4 ft is more string than was on the original piece The only had a 15.2 piece so you know the amount left after Brittany whacks off what she needs is going to be LESS than 15.2 ft.

Answer 17

Kyrie, you must first figure the amount that Brittany is going to remove from the string.
She is going to take off 4 pieces each 4/5 of a foot or 4 times 4/5. Does that seem reasonable?

Answer 18

Yes!

Answer 19

So she would need to take off 4 times 4/5 or 16/5.
That is 4 times 4/5
