Ramen purchase a box of candy for himself on the way back to the dorm he ate 2/3 of the candy while he was putting away grocerie

Aleksandr [31]

Answer:

12 chocolates

Step-by-step explanation:

Represent the original number of chocolates by c.

Then (1/4)(2/3)c = 2

Solving this for c, we multiply both sides by 4: (2/3)c = 8

and then multiply both sides by (3/2): c = (3/2)(8) = 12

Originally the box contained 12 chocolates.

franklin school has 3 boys for every 4 girls in the fifth grade. there are 140 students in the 5th grade. How many boys are ther

marin [14]

Answer:

There are 60 boys and 80 girls in Franklin School.

Step-by-step explanation:

"franklin school has 3 boys for every 4 girls in the fifth grade." means that the ratio of boys to girls is: 3:4

It can also be written as 3/4

Also given

Total number of students: 140

We will use ratios to find the number of boys and girls in shool.

First of all, we have to calculate the sum of ratio which is: 3+4 = 7

Let b be the number of boys and g be the number of girls

Then

$b = \frac{Ratio\ of\ boys}{Sum\ of\ ratio} * Total\ students\\= \frac{3}{7} * 140\\= 3*20\\=60\\g = \frac{Ratio\ of\ girls}{Sum\ of\ ratio} * Total\ students\\g = \frac{4}{7}*140\\= 4*20\\=80$

Hence,

There are 60 boys and 80 girls in Franklin School.
