Answer:

see explanation

Step-by-step explanation:

- \frac{x}{2} ÷ \frac{5}{7}

• leave the first fraction

• change division to multiplication

• turn the 2nd fraction upside down

= - \frac{x}{2} × \frac{7}{5} ( multiply values on numerators/ denominators )

= - \frac{x(7)}{5(2)}

= - \frac{7x}{10} → B

If you can buy 1⁄3 of a box of chocolates for 6 dollars, how much can you purchase for 4 dollars?
alukav5142 [94]

Answer:

2/9 boxes.

Step-by-step explanation:

6 / 1 / 3 = 4 / b

Cross multiply the two

6b = 4/3

Multiply 1/6 on each side

B = 4 /18

It can be reduced to 2/9.

Feel free to let me know if you need more help! :)
