Mission control needs your math.El control de la misión necesita tus matemáticas.
The station dims to night mode as alarms blink. A cargo log has smudged digits, and only a careful navigator can rebuild each division and spot where a zero went missing.
La estación pasa al modo nocturno y las alarmas parpadean. Un registro de carga tiene dígitos borrosos, y solo un navegante cuidadoso puede reconstruir cada división y ver dónde se perdió un cero.

- The station must load 3,360 ration packs equally into 14 storage pods. Solve it with long division. Name each step — divide, multiply, subtract, bring down — and check your answer by multiplying.
- Orbit Station has 6,327 food packets to share equally among 3 storage modules. How many packets does each module get?
- The lab has 487 sample tubes. Each rack holds 12 tubes. How many racks are needed to hold every tube?
- A crew has 275 meal pouches for a 12-day mission. They want the same number of pouches each day. Which statement is correct?
- They can use 22 pouches each day, with 11 pouches left over
- They can use 23 pouches each day, with none left over
- They can use 11 pouches each day, with 22 pouches left over
- They can use 27 pouches each day, with 5 pouches left over
- Run the long-division cycle for 1,404 ÷ 12 = 117. For each step, fill in the quotient digit, the product with 12, and what is left after subtracting.

- Farah divides 4,208 ÷ 4 with long division.
- Nikhil divides 150 ÷ 7 by guessing the quotient and then subtracting.
- Dmitri divides 1,248 ÷ 8 and gets 181.
- A shuttle seats 6 trainees. There are 89 trainees. Kwame says 14 shuttles are enough because 89 ÷ 6 = 14 R5. Mei-Ling says 15 shuttles are needed. Who is right?
- Kwame, because the quotient is 14
- Mei-Ling: 15 shuttles cover all 89.
- Kwame, because 14 × 6 = 84 is close to 89
- Neither, because 89 ÷ 6 should be 15 R−1
- What is the best next move?
- Divide 5 into the 2 alone and ignore the leftover 2.
- Write R2 next to the 1 and stop, because 7 − 5 is done.
- Start over and divide 5 into all of 7,215 again.
- Bring down the next digit, 2, to make 22.
