## anonymous one year ago Clark has 7 and 1 over 2 feet of wire. Part A: How many 3 over 4 foot pieces can Clark cut from the 7 and 1 over 2 feet of wire? Show your work. Part B: Using the information in Part A, interpret the meaning of the quotient in terms of the two fractions given.

Part A: This is a division problem. You need to divide 7 1/2 by 3/4

First, write 7 1/2 as a fraction. Then divide that fraction by 3/4.

4. anonymous

ok

5. mathstudent55

Do you know how to change a mixed numeral into a fraction?

6. anonymous

kinda

7. Michele_Laino

we can write this: $\Large 7\;\frac{1}{2} = 7 + \frac{1}{2} = ...?$

ok

To write a mixed numeral as a fraction, multiply the number by the denominator and add the numerator. That is the numerator of the fration. The denominator is the same you had.

Ok. So far I changed the mixed numeral into a fractions. Now we need to divide a fraction by a fraction. Do you know how to divide a fraction by a fraction?

13. anonymous

nope i was never good at it

14. mathstudent55

No problem. I'll help you with it. Do you know how to multiply a fraction by a fraction?

15. mathstudent55

To multiply fractions together, multiply together the numerators and multiply together the denominators. Then reduce if possible, To divide a fraction by a fraction, change the division into a multiplication by flipping the second fraction. Then multiply the fractions.
