concrete mix
1 kilogram 2.2 pounds
How many quarts of water, rounded to the nearest tenth, does Sylvie need to add to 80 kilograms of concrete mix?

Answer 1

Step-by-step explanation:

that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.

so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.

she should add 1 quart of water to every 26.7 pounds of concrete mix.

80 kg = 80×2.2 pounds = 176 pounds.

we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.

176/26.7 = 6.5917603... quarts of water needed.

that would be rounded 6.6 quarts of water.
