Find common denominators for three sevens and one and half

Answers

Answer 1

Answer: 3/7 and 1 1/2

Now look at the two denominators: 7 and 2.

Because 7 and 2 are relatively prime, their least common multiple is:
7*2= 14

Therefore, 14 is a common denominator for 3/7 and 1 1/2.

Hope this helps~

Answer 2

Answer: 3/7 and 1/2 14 is the common denominator at the end it is 6/14 and 7/14

Mr. Willett was taking 3 students on a hiking excursion. He had 2 2⁄3 pounds of trail mix to split between the students. How many pounds trail mix did each student get?

Answers

Answer:

4/3 each student

Step-by-step explanation:

2+ $(2)/(3)$ = $(8)/(3)$

if there are 3 students, we should split the total amount of trail mix by 3

$(8)/(3)$ ÷3=8/6= 4/3 each student

What does x-4over5=6over7 what doesx=

Answers

$x-(4)/(5)=(6)/(7)$

Pass the $(4)/(5)$ but change the signal

$x=(6)/(7)+(4)/(5)$

now we have to make the minimum common multiple of 7 and 5, this number will be 35 therefore

$x=(6*5)/(35)+(4*7)/(35)$

$x=(30)/(35)+(28)/(35)$

now we can add both

$x=(30)/(35)+(28)/(35)$

$x=(30+28)/(35)$

$\boxed{\boxed{x=(58)/(35)}}$

Ami purchases 27 T-shirts for a certain amount of money. Using m for the total amount of money in dollars that Ami spent on T-shirts, write an expression that represents how much one T-shirt costs

Answers

so total money=m
cost=total money
cost=number of tshirts times cost per tshirt
subsitute
m=27 times cost per shirt
to solve for cost per 1 shirt, divide both sides by 27
$(m)/(27)$ =cost per 1 shirt

answer is 1 t-shirt costs $(m)/(27)$

m = the total amount of money spent
y = how much each t-shirt costs
m / 27 = y
because:
y x 27 = m
so the equation is:
>m/27 = y

You are going to the movie theater with your parents and your 8 year-old brother. Adult tickets cost $8, ages 10 -18 cost $7.25 and under age 10 cost $4.25. If you spent an additional $20 on soda and popcorn, what is the total cost of your trip to the movie theater

Answers

total cost = 47.25 if your age is between 10 - 18

Answer:

The answer is $47.50

Step-by-step explanation:

All you have to do is add up the price of each person attending with what age price for each and then add the additional $20 for the sodas and popcorn.

Two parents = 8.00 + 8.00 = $16.00

"You" would most likely be student price, so.. = $7.25

And 8 year-old little brother is under 10, so.. = $4.25

Adding up those three prices we get $27.50, now all to do is add the additional drinks and snacks price. 27.50 + 20.00 = $47.50

How many positive factors does 2023 have?

Answers

Step-by-step explanation:

1 and 2023 yes as standard.

2 no (not an even number).

3 no (sum of the digits is 7 and not divisible by 3).

4 no (not an even number)

5 no (2023 dies not end with 5 or 0)

6 no (not an even number)

7 yes. and therefore also 2023/7 = 289

7 has no other factors, so 289 is the remaining part with potentially other prime factors.

289 = 17², so 17 is another factor.

but 17 is again a prime number and has no other factors.

2023 = 7×17×17

and so, 7×17 = 119 is also a factor of 2023.

so, we have as factors :

1, 7, 17, 119, 289, 2023

that means 6 factorsin2023.

It takes a biker 1/2 hours to ride 8/3 miles. What is the biker's rate,in miles per hour?

Answers

Answer:

The biker is traveling at $5(1)/(3)$ miles per hour.

Step-by-step explanation:

(r = rate)

(d = distance)

(t = time)

$(8)/(3)$ ÷ $(1)/(2)$ = $5(1)/(3)$
