Example Question #21 : Number & Operations With Fractions
Zach cleaned of the house and Alex cleaned of the house. How much more of the house did Alex clean?
In order to solve this problem, we first need to make common denominators.
Now that we have common denominators, we can subtract the fractions. Remember, when we subtract fractions, the denominator stays the same, we only subtract the numerator.
Example Question #871 : Common Core Math: Grade 5
Lily pulled of the weeds and Rose pulled . How much more of the weeds did Rose pull?
In order to solve this problem, we first need to make common denominators.
Now that we have common denominators, we can subtract the fractions. Remember, when we subtract fractions, the denominator stays the same, we only subtract the numerator.
Example Question #23 : Number & Operations With Fractions
Sally drank of the milk and Sam drank . How much more of the milk did Sam drink?
In order to solve this problem, we first need to make common denominators.
Now that we have common denominators, we can subtract the fractions. Remember, when we subtract fractions, the denominator stays the same, we only subtract the numerator.
Example Question #24 : Number & Operations With Fractions
Jake ate of the popcorn and Dave ate of the popcorn. How much more of the popcorn did Dave eat?
In order to solve this problem, we first need to make common denominators.
Now that we have common denominators, we can add the fractions. Remember, when we add fractions, the denominator stays the same, we only add the numerator.
can be reduced by dividing by both sides.
Example Question #161 : Fractions
When multiplying fractions you simply multiply the numerators to find the numerator of the product, and multiply the denominators to find the denominator of the product.
So, our product is .
Since both of these numbers are divisible by three, we simplify.
Our final answer is .
Example Question #162 : Fractions
Which is the greater quantity?
(a)
(b)
(a) is greater
(a) and (b) are equal
It is impossible to tell from the information given
(b) is greater
(a) is greater
Rewrite the mixed numbers as improper fractions, then multiply across:
Example Question #163 : Fractions
Which is the greater quantity?
(a)
(b)
(b) is greater
(a) and (b) are equal
(a) is greater
It is impossible to tell from the information given
(a) and (b) are equal
Rewrite the factors as improper fractions, then multiply across:
Example Question #164 : Fractions
Which is the greater quantity?
(a)
(b)
(b) is greater
It is impossible to tell from the information given
(a) is greater
(a) and (b) are equal
(a) and (b) are equal
(a)
Divide by moving the decimal point right two places in both numbers:
(b)
Cross-cancel:
, so
Example Question #165 : Fractions
Which is the greater quantity?
(A)
(B)
(B) is greater
(A) and (B) are equal
(A) is greater
It is impossible to determine which is greater from the information given
(B) is greater
, so
, so , making (B) greater.
Example Question #166 : Fractions
Which is the greater quantity?
(A)
(B)
It is impossible to determine which is greater from the information given
(B) is greater
(A) is greater
(A) and (B) are equal
(B) is greater
Since , , so (B) is greater.
