Find 6 3/4 - 4 11/12. Write your answer in simplest form.
Mrrafil [7]

Answer:

1 5/6

Step-by-step explanation:

first convert to /12 and put the wholes in the fraction:

6 3/4 = 81/12

4 11/12 = 59/12

Then perform the subtraction

81/12 - 59/12 = 22/12

... and simplify

22/12 = 11/6

separate the wholes

11/6 = 6/6 + 5/6 = 1 5/6

Lourdes are 5/6 of a brownie. Zachary are 4/5 of a brownie of the same size. Who are more brownies?
OleMash [197]

Answer:

Lourdes has more brownies.

Step-by-step explanation:

First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.

24/30 < 25/30. So Lourdes has the most brownies!

Part B In part A you simplified the expression 4+ 16 - (4)5) What other type of expression does this expression remind you 2 of?
WARRIOR [948]

The expression in part A is similar to the quadratic formula. So, it’s likely that complex numbers can help us solve quadratic equations that have imaginary solutions and that we would have labeled as having no solution if using only real numbers.
