Question

1. a saltwater solution for an aquarium calls for 35 parts salt to 1000 parts water. tareq used 7 tablespoons of salt and 200 tablespoons of water.

Explanation:

Assuming the question is to check if Tareq's ratio is correct (or find the correct amount), we use proportions (Mathematics - Algebra/Statistics).

Step1: Define the ratio

The required ratio is $\frac{\text{salt}}{\text{water}} = \frac{35}{1000}$. Simplify: $\frac{35}{1000} = \frac{7}{200}$ (divide numerator and denominator by 5: $35\div5 = 7$, $1000\div5 = 200$).

Step2: Check Tareq's ratio

Tareq's ratio is $\frac{7}{200}$, which matches the simplified required ratio.

Answer:

Tareq's ratio is correct (or the amount is proportional). If finding the correct water for 7 salt: $200$ tablespoons (matches); or salt for 200 water: $7$ tablespoons (matches).
