What is k+3 3/4 = 5 2/3 - 1 1/3

Answers

Answer 1
Answer: k+3 3/4=5 2/3-1 1/3
k+3 3/4=4 1/3
lets find the lcm first then multiply both sides by it but first change it to improper fraction
LCM is  12

[k+15/4]=[13/3]12
12k+45=52
12k=7
k=7/12

Megan has $45.12 in her purse. She spends $7.89 for lunch and $21.25 for a pair of sunglasses. Which is the best estimate for the amount of money Megan has left?Responses




$12


$16




$20




$24

Answers

Answer: To find the best estimate for the amount of money Megan has left, we need to subtract the amount she spent from the initial amount she had. Megan started with $45.12, and she spent $7.89 for lunch and $21.25 for sunglasses.

First, let's subtract $7.89 from $45.12:

$45.12 - $7.89 = $37.23

Next, let's subtract $21.25 from $37.23:

$37.23 - $21.25 = $15.98

So, the best estimate for the amount of money Megan has left is $15.98.

Out of the given options, the closest estimate to $15.98 is $16. Therefore, the correct answer is $16.

Answer:

$16
