of a pound of peanuts to divide equally between 2 friends.
a. What is the weight of peanuts in pounds that each friend will
receive?
b. One of Janine's friends already had 3/4 pounds of peanuts before Janine gave her more. However, this friend wants to end with 2 pounds of peanuts. How much more pounds of peanuts does this friend need to get to end up with 2 pounds of peanuts?​

Answer 1

Answer:

Part a) Each friend will receive $\frac{3}{10}\ pounds$

Part b) $\frac{19}{20}\ pounds$  or $0.95\ pounds$

Step-by-step explanation:

Part a)

we know that

To calculate the weight of peanuts in pounds that each friend will

receive, divide the total pounds of peanuts by two

so

$\frac{(3/5)}{2}=\frac{3}{10}\ pounds$

Part b)

Let

x-----> pounds of extra peanuts the friend needs to end up with 2 pounds of peanuts

we know that

$2=x+\frac{3}{10}+\frac{3}{4}$

Solve for x

$x=2-(\frac{3}{10}+\frac{3}{4})$

Multiply by 40 both sides

$40x=80-(12+30)$

$40x=38$

$x=\frac{38}{40}\ pounds$

Simplify

$x=\frac{19}{20}\ pounds$  or $x=0.95\ pounds$
