Answer:

B it was b when I answered

Answer:

The answer is B. 5/1

Step-by-step explanation:

Convert them into improper fractions: it would become 65/6 divided by 13/6. After that do the process of dividing fractions: keep the first one the same, change the sign to multiplication and flip the second fraction to 6/13. After that, multiply the two numerators and denominators to get 390/78. This simplifies to the whole number 5, but in your case, 5/1.

A sales tax of 7% was added to the $30 price of a jacket. What was the total cost of the jacket?

$21.00
$30.07
$27.90
$32.10

Answers

It would be $32.10!
Explanation:
Every time you need to calculate this type of question, a superrrr easy way to do it is just google (the sales tax percent) of (the price of the item) like for this one it’s 7% of 30 and then the answer it gives (2.1) is the sales price so you just do 30+2.1=32.10 (add a zero at the end because it’s money!) hope this helped for the future :))

Answer:

False

Step-by-step explanation:

Bagel stop sells 15 bagels for 6 dollars, dividing 15/6, you get that you get 2.5 bagels per dollar. Whilst Yummy bagels sells 35 bagels for 14 dollars. Diving 35/14 you get 2.5 as well. Therefore this is false.

Write equivalent fractions for
9/10
and
1/5
using the least common denominator.

Type the fractions, using a slash ( / ) to separate the numerator and denominator.

9/10=

1/5=

Answers

Answer: 9/10 stays the same and 1/5 turns into 2/10

Step-by-step explanation: The least common denominator is 10. 9/10 stays the same because the denominator is 10 in it. 1/5 turns into 2/10 because you have to multiply the numerator and denominator by 2 so 1/5 turns into 2/10.

9/10 stays the same and 1/5 turns into 2/10 for the given fractions.

What is the least common denominator method?

The least common denominator is 10. 9/10 stays the same because the denominator is 10 in it. 1/5 turns into 2/10 because you have to multiply the numerator and denominator by 2 so 1/5 turns into 2/10.

List the multiples of both denominators until you discover the smallest multiple that both share to get the least common denominator. 28 must be the least common denominator for these two fractions since it is the first shared multiple of 4 and 7, respectively.

Hence, 9/10 stays the same, and 1/5 turns into 2/10 for the given fractions.
