A)Divide 3\ 8 by 6\ 7
.
B)
Convert 3 \8 and 6\ 7 to fractions with a common denominator.

C)
Find a common numerator and multiply the denominators by this number.
Eliminate

D)
Find a number between 3 and 6 to get the numerator and add 8 and 7 for the denominator.

Answers

So,

In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.

LCM of 8 and 7: 56

Multiply each fraction by the appropriate form of 1:
$(3)/(8) * (7)/(7)\ AND \ (6)/(7) * (8)/(8)$

$(21)/(56)\ AND\ (48)/(56)$

We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.

The correct option is B.

Step-by-step explanation:

A pack of paper costs $3.75 including tax. Mr. Cooper wants to purchase packs of paper for his class and has a $20 budget. Write an inequality to solve for the number of packs of paper Mr. Cooper can purchase with his budget.

Answers

Answer:

$3.75x\leq 20$

5 packs of paper.

Step-by-step explanation:

Let x be the number of packs of paper.

We have been given that a pack of paper costs $3.75 including tax. The price of x paper packs would be $3.75x$ .

Since Mr. Cooper has a $20 budget, so the cost of x paper pack should be lees than or equal to 20.

We can represent this information in an inequality as:

$3.75x\leq 20$

$(3.75x)/(3.75)\leq (20)/(3.75)$

$x\leq 5.333$

Since we can purchase whole number of paper packs, therefore, Mr. Cooper can purchase 5 packs of paper with his budget.

3.75p<=20

divide by 3.75

p < 5 1/3

he can purchase 5 packs of paper
