You can set both fractions to have the same denominator by multiplying 6/8 (both the 6 and 8) by 2 to keep the value of the fraction, while turning the denominator to 16. So you get 12/16=y/16.
That means for the equation to be true y has to be 12.

Hope this helps!

Negative 4 equals r/20 minus 5

levacccp [35]

Answer: r = - 20

Step-by-step explanation:

$-4 = \frac{r}{20} - 5$

$\frac{r}{20} = 4-5$

$\frac{r}{20}=-1$

$\frac{r}{20}*20 = -1 * 20$

$r = -20$

Mary has 60 candy pieces and 45 chocolates. She wants to distribute the candy to her little sister's friends at her birthday par

Anna11 [10]

Answer:

5 friends

Step-by-step explanation:

Candy pieces = 60

Chocolate = 45

What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?

To calculate this, find the lowest factor of 60 and 45

60:

Factors = 2, 4, 5, 6,

45:

Factors= 3, 5, 9

The lowest common factor of 60 and 45 is 5

The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5

That is

If there are 5 friends at the birthday party

60 candy pieces among 5 friends

= 60/5

= 12 pieces each

45 chocolate among 5 friends

= 45/5

= 9 each
