Put the ratios into fraction form. Since you do not know how many problems, replace it with an unknown number a.k.a. a variable.

10/30 = x/60

Since you can get 30 to 60 by multiplying by 2, multiply everything on the left side by 2.

Then, you get 20/60, which means 20 = x. So, he can complete 20 minutes an hour.

ExtremeBDS [4]

Answer:

Cyrus needs to order 3 full pizzas to feed his 11 friends .

Step-by-step explanation:

The number of friends invited = 11

Share of pizza for each friend = 1/4 pizza

Now, as 1 friend eats 1/4 of a pizza.

⇒ 11 friends eat = $11 \times \frac{1}{4} = 2.75$

So, 11 friends can eat 2 .75 pizza.

Since pizza come as a whole number.

And 2. 75 is nearly equal to 3.00

Hence, Cyrus needs to order 3 full pizzas to feed his 11 friends .
