8th Grade: Instruments that looks like a violin - uses strings with a total length 5 3/4 ft. per violin. How many can be made with 24 ft of string.

Answer 1

5 3/4 = 23/4

24 ÷ (23/4) = 24(4/23) = 96/23 = 4 4/23

Well, we can make 4 instruments with some string left over.

Answer 2

Use the following STEPS to solve this problem:

STEP 1)

Convert the fraction to a decimal*

5^3/4 ft converts to 5.75 ft.

STEP 2)

You have 24 ft of string so you need to DIVIDE - 24 ft / 5.75 ft = 4^4/23

ANSWER:

**Make sure to answer your question in a FULL sentence. And don't forget to use punctuation!!

You can make 4 violins with 24 feet of string.

*Review of conversion of fractions: (ugh)

NOTE: I am assuming your teacher allows you to use a CALCULATOR. This is the 21st century after all!

When your problem has a fraction like 4/23 or something weird and complicated like that you can convert it to a decimal to make the number easier to work with:

You have 5^3/4 as your fraction. You can simply convert the 3/4 to .75 by DIVIDING 3 by 4. Try it on your calculator.

Same thing with the 4/23 Just divide 4 by 23! You will have 4.17 ft (or 4.2 ft if your rounding) of string left over. No enough to make a fifth violin.

Good luck!
