Answer 1

Answer:

3550ml

Step-by-step explanation:

Thomas made 8,700 ml of Soup.

He packed 1.6L in his kid's lunch.

Since our result is required in milliliters, it is more practical to convert all units to milliliters.

1 Litre=1000 millilitre

1.6 Litre=1.6 X 1000 ml =1600ml

Since Thomas packed 1600ml of soup, the remaining volume of soup is determined by the expression:

Total Soup Prepared - Volume of Soup Packed= 8700-1600=7100ml

Remaining Soup=7100ml

Since he froze half of the remaining.

½ of 7100ml=3550ml

Thomas froze 3550ml of soup.

Answer 2

Answer:

Step-by-step explanation:

Given:

Volume of soup made, V = 8700 ml

Packed, Vk = 1.6 l

Froze, Vf of the remaining = 1/2 of the remaining, Vr

Volume of soup remaining, Vr = 8700 × 10^-3 l - 1.6 l

= 7.1 l

Volume froze, Vf = 1/2 × Vr

= 7.1/2

= 3.55 l

Converting to ml,

= 3.55 × 10^3 ml

= 3550 ml
