Word problem: U.S. Customary weight to metric mass
Two steps in a fixed order. Multiply by however many you need, then convert once at the end. Doing it the other way round works too, but converting first gives you an awkward number to multiply.

ALEKS randomizes the numbers each attempt, but the question shape stays the same. Here are three example versions you might see.
A recipe needs 12 oz of sugar per batch. Someone is making 3 batches. The shop sells sugar by the gram.
How many grams are needed? Use 1 oz = 28 g. Type just the number.
9 oz of butter per batch, 5 batches, sold by the gram.
How many grams? Use 1 oz = 28 g. Type just the number.
14 oz per batch, 6 batches, 1 oz = 28 g.
A student answered 392 g. What is the correct answer? Type just the number.
While studying abroad, Priya wants to bake 4 batches of her grandmother's bread to share with her flatmates. The recipe calls for 18 oz of flour for each batch. The local shop sells flour by the gram. How many grams of flour should Priya buy?
Use 1 oz = 28 g and do not round any computations.
Which order?
Total the ounces
Multiply or divide?
Convert
Two steps, and the order is yours
4 × 18 = 72 oz, then 72 × 28 = 2,016 g.
Converting first would also work, because multiplication does not care what order you do it in. What does not work is forgetting the count altogether, which gives 504 g and answers a question about one batch instead of four. That is the mark this question is really testing.
