Answer:

You would get 50 coins in that time.

Step-by-step explanation:

To find this, we first need to find the unit rate. We can get that by dividing the amount of coins by the amount of time.

15 coins/ 30 mins = .5 coins per minute.

Now, we have 100 minutes in the second part of the problem, so we multiply the rate by that amount of time.

.5 coins per min * 100 mins = 50 coins

Ella grew 3 over 4 of an inch last year. Ben grew 2 over 3 of an inch last year. How much more did Ella grow than Ben last year?

IrinaK [193]

Answer:

Ella grew $\frac{1}{12}$ of an inch more

Step-by-step explanation:

For this problem, you want to subtract Ben's growth from Ella's.

This expression would be $\frac{3}{4}$ - $\frac{2}{3}$ .

To work these out, they must have the same denominator (which should be the lowest common multiple or LCM).

In this case, the LCM is 12, so you want to multiply each side so the denominator is 12. This means the first fraction should be multiplied by $\frac{3}{3}$ and the second by $\frac{4}{4}$ .

This makes the expression $\frac{9}{12}$ - $\frac{8}{12}$ , which equals $\frac{1}{12}$ .

A shelter has 5 dogs for every 4.cats. How many cats will the shelter have if they have 25 dogs?

olga_2 [115]

Answer:

20 cats

Step-by-step explanation:

A proportion has to be setup to answer this

5/4 = 25/x

x represents the missing number of cats

This fraction represents the relationship amongst dogs and cats

----

To solve cross multiply

5x = 100

(let me down below if you need an explanation on how to cross multiply)

Divide both sides by 5 in order to get the variable by itself

100/5 = 20

x = 20

The shelter has 20 cats
