Vlad [161]

Answer: Lucy ate more pizzas because he ate more inches of pizza than Anthony.

Step-by-step explanation:

Anthony eats 2 slices of a large 18 inch pizza. Total number of slice in the 18 inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

18 / 8 = 2.25 inches

Anthony ate 2 ×2.25 = 4.5 inches of pizza.

Lucy eats 4 slices of a 12 inch pizza.

Total number of slice in the 12inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

12 / 8 = 1.5 inches

Lucy ate 4 × 1.5 = 6 inches of pizza.

Lucy ate more pizzas because he ate more inches of pizza than Anthony.

Caleb and Suzanne each have a pile of blue and white chips. Caleb determines in his pile,three out of every four chips is blue.

Artist 52 [7]

Answer:

Total number of chips Caleb have = 8

Total number of chips Suzanne have = 30

Step-by-step explanation:

In Caleb case -

Three out of every four chips is blue

⇒ If Caleb has total chips = 4

Then Blue chips = 3

⇒White chips = 4 - 3 = 1

Now,

If Caleb have 6 blue chips

⇒3 Blue chips = 4 total chips

1 Blue chip = $\frac{4}{3}$ total chips

⇒6 blue chips = $\frac{4}{3}$ ×6 = 4×2 = 8 total chips

∴ we get

Number of chips become = 8

In Suzanne case -

One out of every five chips are blue.

⇒ If Suzanne has total chips = 5

Then Blue chips = 1

⇒White chips = 5 - 1 = 4

Now,

If Suzanne have 6 blue chips

⇒1 Blue chips = 5 total chips

⇒6 blue chips = 5×6 = 30 total chips

∴ we get

Number of chips become = 30
