Fractions show a _____ being divided by the ______

Answer 0

Fractions show a part being divided by the whole

Question 1

What do fractions show?

Answer 1

Fractions show the division of the number by the denominator

Question 2

Fractions are numbers so they can be _____,______,______,______

Answer 2

Added, Subtracted, Multiplied, or Divided

Question 3

When a fraction is divided by a whole number how does the answer compare with the dividend (the original fraction)?

Answer 3

The quotient is smaller than the original fraction. When this happens, our answer is reasonable.

Question 4

What is Measurable Division?

Answer 4

Measurable division is when you know the original amount and the size or measure of one part, and we can find the number parts.

Question 5

How does the general rule look like?

Answer 5

a/c ➗ b/c = a/b

Question 6

When can we use the general rule?

Answer 6

We can use the general rule when the fractions have the same denominator

Question 7

What is one possible way to solve two fractions with different denominators?

Answer 7

We can use equivalent fractions in order to solve.

Question 8

What do you do if fractions do not have equivalent fractions?

Answer 8

You can divide the numerator by the denominator

Question 9

What is dividing a fraction to its equivalent like?

Answer 9

Dividing a fraction to its equivalent to multiplying by its reciprocal, or multiplicative inverses.

Question 10

What is the similarities between dividing FRACTIONS with MIXED NUMBERS and dividing MIXED NUMBERS by FRACTIONS?

Answer 10

We can use the invert and multiply method for both types

Question 11

What are the differences between dividing FRACTION by MIXED NUMBER and MIXED NUMBER by FRACTION?

Answer 11

It is necessary to change the mixed number into a fraction greater than one before invert and multiply method, if the mixed number is the divisor.

Question 12

When fractions have larger denominators…

Answer 12

It would be more difficult to find common denominators in order to add and subtract

Question 13

When a problem is solved by regrouping, what is easier to borrow: decimals or fractions?

Answer 13

Decimals

Question 14

What U-Turn can be used for dividing fractions?

Answer 14

Tape Diagrams

Question 15

What do you do to make two fractions have equivalent denominators?

Answer 15

You have to find their LCM

Question 16

How do you find the product of decimals?

Answer 16

You can use the standard algorithm, or partial products

Question 17

How do you locate the location of the decimal point in a number?

Answer 17

Calculate the number of digits in each factor. The sum represents the number of decimal digits in the product

Question 18

What is another way to solve a problem that deals with adding and multiplying decimals?

Answer 18

Estimation

Question 19

How do you do the invert and multiply method?

Answer 19

Keep the dividend, change division to multiplication, and flip the divisor

Question 20

What are the steps used to change a division question with decimals to a division question with whole numbers?

Answer 20

If the divisor is not a whole number, rewriet the divisor as a whole number by moving the decimal point. Then, move the decimal point in the divident the same number of pplace values as you did in the divisor

Question 21

What is unit rate?

Answer 21

A quantity of 1 (MPH, Money per hour, Amount sold per hour,)

Question 22

Solve 865.1475 / 47.25

Answer 22

842.945

Question 23

What are the steps that you need to chnge a division question with a decimal to a division question with whole numbers?

Answer 23

If the divisor isn’t a whole number, rewrite the divisor as a whole number by moving the decimal point. The number of times the decimal point is moved in the divisor is the number of times it should also be moved on the dividend.

Question 24

What is GCF?

Answer 24

The greatest whole number which is a common factor of variables a and b.

Question 25

What is LCM?

Answer 25

The least whole number that is a common multiple of a and b

Question 26

How do you find the GCF?

Answer 26

1. List factor pairs in order using a 2 column chart 2. Circle common factors that appear on both lists 3. Place a triangle on the greatest factor out of all the circled factors.

Question 27

How do you find the LCM?

Answer 27

1. List the first 10 multiples of each number 2. Circle the multiples that appear on both lists 3. Place a trinagle on the multiple that is the least.

Question 28

How do you use prime factors to solve?

Answer 28

1. Make a prime factor tree 2. Circle each pair of numbers that appear on both trees 3. Use a venn diagram to compare the factors 4. Multiply each pair of factors to find the GCF
