Question

day 3

1. how many pets do the students have in all?
2. what time is shown on the clock?
3. which unit would you use to measure the amount of water in a glass? a. gallon b. gram c. cup

Explanation:

Step1: Count pet - paw symbols for each type of pet

Dogs: 8 paw - symbols, Cats: 6 paw - symbols, Fish: 5 paw - symbols, Birds: 2 paw - symbols.

Step2: Calculate the number of pets for each type

Dogs: \(8\times2 = 16\) pets, Cats: \(6\times2=12\) pets, Fish: \(5\times2 = 10\) pets, Birds: \(2\times2=4\) pets.

Step3: Sum up the number of all pets

\(16 + 12+10 + 4=42\) pets.

For the clock - reading:
The hour hand is between 4 and 5, and the minute hand is on 27 (since each small division between numbers on the clock represents 1 minute and the minute hand is at the 7th small - division after 5). So the time is 4:27.

For the unit of measurement:
A gallon is too large for the amount of water in a glass. A gram is a unit of mass, not volume for liquid in common usage for this context. A cup is a suitable unit for measuring the amount of water in a glass.

Answer:

1. 42
2. 4:27
3. C. cup
