30 treadmills to 36 elliptical machines the ratio in simplest form

Goshia [24]

30 treadmills : 36 ellipticals
this could be written in a few ways, but i am going to write it as a fraction. since treadmills come first, you put 30/36.

now that you have your fraction you have to find the GCF (greatest common factor) of the two numbers. the GCF is 6, so you have to divide 30 treadmills by 6, and 36 ellipticals by 6.
30/6=5
36/6=6

5/6 or 5:6 is the simplified ratio of treadmills to ellipticals

Elena is feeding her neighbor's dogs each dog gets two thirds cup of dog food and she uses three and one third cups of food how

MrRa [10]

Answer:

Total number of dogs is 5.

Step-by-step explanation:

Cups of food each dog gets= $\frac{2}{3}$

Here,each dog eats two-third cups of dog food.

Amount of dog food used= $\frac{10}{3}$

A total of three and one-third cups of food is used up.

Let the number of dogs be x.

To find the number of dogs,divide total dog food used by the amount of dog food eaten by each dog.

Hence, x = $\frac{\frac{10}{3} }{\frac{2}{3} }$

x = $\frac{10}{2}$

x =5

Chance bought a surf board for 249. Now it's on sale for 221.10. Find the percent of the discount

Masteriza [31]

Answer:

Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.

Solution:

Step 1:

Bought price= RS.249

Sale price=RS.221.10

Step 2:

Discount = bought price - sales price

Discount = 249 - 221.10

Discount = 27.9

Step 3:

Discount Percent = $\frac{\text {Discount}}{M R P} \times 100$

Substitute the value for Discount which we found in step 2 in the above formulae

Discount Percent = $\frac{27.9}{249} \times 100$

On simplification, we get

$\frac{27.9}{249} \times 100$

Discount Percent = 11.20%

Result:

Hence from the given data, we got the discount percent is 11.20%
