The length of a ribbon is 3/4 meter.Sun Yi needs pieces measuring 1/3 meter for an art project.what is the greatest number of pieces measuring 1/3 meter that can be cut from the ribbon? How much ribbon will be left after Sun Yi cuts the ribbon? Explain your reasoning

Answers

The correct answer is:

2 pieces, with 1/12 m left over.

Explanation:

To find the number of 1/3 meter pieces she can cut from a 3/4 meter ribbon, we divide:

3/4÷1/3

To divide fractions, flip the second one and multiply:

3/4×3/1

To multiply fractions, multiply straight across:

(3*3)/(4*1) = 9/4

4 will go into 9 two times with 1 left over, so this simplifies to 2 1/4; this means she can cut 2 pieces this length.

2 pieces that are 1/3 meter long is a total of 2(1/3) = 2/3 m. To find out how much is left, subtract:

3/4 - 2/3

Common denominator is 12:

3/4 = 9/12 and 2/3 = 8/12

9/12 - 8/12 = 1/12

There is 1/12 of a meter left.

Answer:

She can make maximum 2 pieces

Amount left = $(1)/(12)$ m

Explanation:

1- getting the maximum number of pieces:

We know that the total length is $(3)/(4)$ m and that each piece would measure $(1)/(3)$

To get the number of pieces, we would simply divide the total length by the length of each piece as follows:

number of pieces = $(3)/(4) / (1)/(3) = (3)/(4) * (3)/(1) = (9)/(4) = 2.25$ pieces

We will need to round down to get the maximum number of pieces.

This means that the maximum number of pieces that she can cut is 2 pieces

2- getting the leftover:

We calculated that she can make two pieces each of length $(1)/(3)$ m

This means that:

total length of two pieces = $2 * (1)/(3) = (2)/(3)$ m

We know that the total length is $(3)/(4)$ m

This means that:

leftover = $(3)/(4) - (2)/(3) = (1)/(12)$ m

How do you turn -3 1/3 into a negative fraction decimal

Answers

Dear Joanna243, what do you mean by a "negative fraction decimal". You can't have a fraction and a decimal at the same time. I'll solve it anyway. Take 1/3 and do 1÷3 to get approximately 0.33, then you plug the -3 with 0.33 to get -3.33

First you do 1÷3=0.333.......
1/3 can be turn into 0.33...

So, after that it will be -3.33......
If you round it will be -3.33

What are the disadvantages to solving a quadratic equation by factoring

Answers

Answer:

-factoring may not work; for instance, factoring will not find solutions that are not integers.

-very difficult to use on any quadratic that doesn't have extremely easy numbers. In most cases, factoring will only be simple if the answers are integers or commonly used fractions.
