Answer:

a) Pam had less water than apple juice.

Water < Soda < Apple juice

Explanation:

Converting the fraction into decimals,

→ Soda left = 1/2 = 0.5 litres

→ Water left = 1/5 = 0.2 litres

→ Apple juice left = 8/10 = 0.8 litres

Let's order them in ascending order,

→ 0.2 < 0.5 < 0.8

→ 1/5 < 1/2 < 8/10

Water left < Soda left < Apple juice left

Now the applicable options is,

→ Pam had less water than apple juice.

Hence, option (a) is correct answer.

Answer:

A) Pam had less water left over than apple juice.

Explanation:

Given amounts of drinks left over:


  • (1)/(2)\; \sf liter \;of \;soda

  • (1)/(5)\; \sf liter \;of \;water

  • (8)/(10)\; \sf liter \;of \;apple\;juice

To compare the amounts of drinks left over, convert the fractions into equivalent fractions that have the same denominator.

The denominators of the three fractions are 2, 5 and 10.

The lowest common multiple of the denominators is 10.

Therefore, rewrite the first two fractions so that their denominators are also 10.


\textsf{Soda}: \quad (1)/(2)=(1 \cdot 5)/(2 \cdot 5)=(5)/(10)


\textsf{Water}: \quad (1)/(5)=(1 \cdot 2)/(5 \cdot 2)=(2)/(10)

Therefore, as:


  • (2)/(10) < (5)/(10) < (8)/(10)

then:

  • water < soda < apple juice

Therefore, Pam had less water left over than apple juice.
