Answer: you have to color in the blocks
Step-by-step explanation: For the first one it says 1.47. So you wold shade in one whole square and then fill out 47 tiny blocks in yellow. Then you would shade in 28 little blocks in blue. For the second one you shade in 1.85 in yellow. To do this shade in one whole square and them 85 little blocks. It then says to take away .3 meaning cross out three little blocks that you shaded in. Hope i could help!!!
You divide each of the ratios by 64:60
This gives;
![\frac{64}{4} : \frac{60}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B64%7D%7B4%7D%20%3A%20%5Cfrac%7B60%7D%7B4%7D%20)
=16:15
Answer: 6.25
create a ratio of 2.5/2 = x/5 and solve for x. First multiple both sides by 10 so you get 12.5 = 2x. Then you get x = 6.25.
You can model this problem using the following inequations:y≥10 and 4 * y + 12 * x <400 ... To find the number of pizzas and people, you have to rewrite the inequations as equations and solve the 2x2 system. That is y = 10 and 4 * Y + 12 * X = 400. Clearing from the second equation X, X = 30 results. Therefore, approximately Jhon can have 10 people and 30 pizzas at his party.
