Answer:

8/5 or 1 3/5

Step-by-step explanation:

2 2/5 = 12/5

1 1/2 = 3/2

Now that we have fractions that are easier to divide, one must understand that the opposite of dividing is multiplying. So if you multiply 12/5 by the reciprocal* of 3/2, which would be 2/3, you would get your answer so...

12 3 12 2 24 8 3

— ÷ — = — × — = — = — <em>or</em> 1 —

5 2 5 3 15 5 5

*the reciprocal is the opposite of the fraction you have. So the denominator would become the numerator, and vise versa.

Can Someone help me with work too. show some work please

In this problem,, we are told that Mr Nelson needs 5 1/2 yards of fabric to make two dresses. the problem then asks us to find out how much fabric it will take to make only one of the dresses. this means that in order to find out how much fabric is needed to make only one of the two dresses,, we need to divide the total amount of fabric by two. the equation will look like the following:
5 1/2 ÷ 2
the first step to solving this is to convert the mixed number to an improper fraction
11/2 ÷ 2
now,, you can turn the 2 into a fraction and changed the sign because dividing is equivalent to multiplying with the reciprocal value.
11/2 × 1/2
you must then multiply the fractions
11/4
finally,, you need to simplify the fraction to find the answer
2 3/4 yards
since you cannot simplify any further,, the correct answer to your question is A, 2 3/4 yards.
let me know if you have any further questions

Solve negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity end quantity.

asambeis [7]

The value of the expression is one eight

<h3>How to solve the expression?</h3>

The expression is given as:

negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity

Rewrite properly as:

-1/5 * (4 - 14) * (1/4)^2

Evaluate the difference

-1/5 * (-10) * (1/4)^2

Evaluate the exponent

-1/5 * (-10) * 1/16

This gives

2 * 1/16

Further, evaluate

1/8

Hence, the value of the expression is one eight
