Question 1

The figure below shows Fred painting the second half of the dog fence. Which number corresponds to the section of the fence that Fred painted?

Accepted Answer

0.5

Answer

Painting the 'second half' of the fence means painting 1/2 of it. To express the fraction 1/2 as a decimal, you divide 1 by 2. This calculation results in 0.5. Therefore, 0.5 correctly represents the section of the fence Fred painted.

Question 2

Liza, Jade, and Mary went out and bought cloth for their party tables.
Liza's fabric measures 1.5 meters.

Jade's fabric measures 1 meter in length.

The length of Mary's fabric is 2.1 meters.

Which of the following statements concerning fabric lengths is correct?

Accepted Answer

Mary's fabric is longer than Liza's.

Answer

To determine the correct statement, compare the lengths of the fabrics: Liza's is 1.5 meters, Jade's is 1 meter, and Mary's is 2.1 meters. Mary's fabric (2.1 m) is the longest of the three. Since 2.1 meters is greater than 1.5 meters, Mary's fabric is indeed longer than Liza's.

Answer

There appears to be a discrepancy between the given height (3.22 meters) and the provided correct answer (32.2 cm). Assuming the correct answer is indeed 32.2 cm, it implies that Rica's height was actually 0.322 meters, not 3.22 meters. To convert meters to centimeters, you multiply the meter value by 100 (since 1 meter = 100 centimeters). Therefore, 0.322 meters * 100 = 32.2 centimeters.

Question 5

Rica stands at a height of 3.22 meters. Rica's height in centimeters is

Accepted Answer

32.2 cm

Answer

The phrasing 'She has half the amount of dolls as she does make up toys' is ambiguous. However, for the given answer (14 ÷ 2 = p) to be correct, it must be interpreted as 'the number of make up toys (p) is half the number of dolls (14).' In this interpretation, you would divide the number of dolls (14) by 2 to find the number of make up toys (p), so p = 7.
