Question

which proportion could you use to convert 7 grams to milligrams?$\frac{10 \text{ milligrams}}{1 \text{ grams}} = \frac{? \text{ milligrams}}{7 \text{ grams}}$$\frac{1,000 \text{ milligrams}}{1 \text{ gram}} = \frac{? \text{ milligrams}}{7 \text{ grams}}$convert.7 grams = $square$ milligramssubmit

Explanation:

Step1: Identify correct conversion proportion

The valid gram-to-milligram ratio is $\frac{1000 \text{ milligrams}}{1 \text{ gram}} = \frac{? \text{ milligrams}}{7 \text{ grams}}$, since 1 gram = 1000 milligrams.

Step2: Solve for unknown milligrams

Cross-multiply to isolate the unknown:
$? = 7 \times 1000$

Answer:

Correct proportion: $\boldsymbol{\frac{1,000 \text{ milligrams}}{1 \text{ gram}} = \frac{? \text{ milligrams}}{7 \text{ grams}}}$
7 grams = $\boldsymbol{7000}$ milligrams
