Hey there! :)

Answer:

The bag is cheaper because one litre is roughly $1.00, compared to the carton which is $1.99 for one litre.

Step-by-step explanation:

Given:

Bag of 4 litre milk = $3.99

Carton of 1 litre milk = $1.99

Find the price per litre for a bag of milk:

$\frac{3.99}{4} = \frac{x}{1}$

Cross multiply:

3.99 = 4x

Divide both sides by 4:

3.99/4 = x.

x = 0.9975 ≈ $1.00

Bag of 1 litre milk ≈ $1.00

Carton of 1 litre milk = $1.99

$1.00 < $1.99

Therefore, the bag is cheaper.

Answer:

$\frac{55}{14}$

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: $1\frac{3}{7} =\frac{10}{7}$ , and $2\frac{3}{4}=\frac{11}{4}$ . Now, we multiply the fraction using the multiplication rule, $\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}$ : $\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}$ .
