Does anybody know how to write 45/70 in simplest form????

Answers

Answer 1

Answer: To reduce a fraction to a simpler form, find a common factor of the numerator and denominator, and divide them both by it. If they have no common factor, then the fraction is in its simplest form.

Just looking at 45 and 70, we know immediately that they're both multiples of 5 .
So let's divide top and bottom by 5 :

45/70 = 9/14 .

That's simpler.

Now, do 9 and 14 have any common factors ? No ? Good.
That means that 9/14 is the simplest form of 45/70.

You didn't have to know what it is. You just had to know how to find it.

Step-by-step explanation:

There are 3 grams of fiber in half cup of oatmeal. there are 1 and 1 eight cups of oatmeal left in a box. determine the approximate number of grams of fiber left in the box. show your work with pictures and explain how you found the number of grams of fiber left.

Answers

There are 3 grams of fiber in 1/2 cup of oatmeal. Therefore, the number of grams of fiber in 1 (which is twice as large as 1/2) cup of oatmeal is:
3 g fiber *2= 6 g fiber.

There is 6 g fiber in 1 cup of oatmeal. Therefore, the number of fiber in 1 1/8 (which is 1 1/8 times as large as 1) cups of oatmeal is:
6 g fiber *(1 1/8)= 6.75 g fiber.

There is 6.75 g of fiber left in the box.

Hope this would help~

Answer=6 3/4 grams

3 grams of fiber x fiber
______________=_________
1/2 cup 1 1/8 cup

Cross multiply
1/2x=3 3/8
divide both sides by 1/2
x=6.75 or 6 3/4
There is 6 3/4 grams of fiber in 1 1/8 cups of oatmeal.

the base of a regular pyramid is a hexagon whose perimeter is 84 feet. the volume of the pyramid is approximately 4,677.85 cubic feet. find the height of the pyramid.

Answers

Answer:

The height of the pyramid is $27.56\ ft$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=(1)/(3)BH$

where

B is the area of the base of the pyramid

H is the height of the pyramid

step 1

Find the area B of the regular hexagonal base

we know that

The perimeter of a regular hexagon is

$P=6b$

where

b is the length side of the hexagon

we have

$P=84\ ft$

substitute

$84=6b$

solve for b

$b=14\ ft$

Remember that the area of a regular hexagon is the same that the area of six equilateral triangles

Determine the area of the six equilateral triangles, applying the formula of the law of sines

$B=6[(1)/(2)b^2sin(60\°)]$

substitute the value of b

$B=6[(1)/(2)(14)^2sin(60\°)]$

$B=509.22\ ft^2$

step 2

Find the height of the pyramid

$V=(1)/(3)BH$

we have

$V=4,677.85\ ft^3$

$B=509.22\ ft^2$

substitute

$4,677.85=(1)/(3)(509.22)H$

solve for H

$14,033.55=(509.22)H$

$H=14,033.55/(509.22)H$

$H=27.56\ ft$
