Frequently asked questions

β–ΈWhat is a proportional relationship?

Two quantities are proportional when their ratio is constant β€” double one and the other doubles. In a table the ratios are all equal, and on a graph the points form a straight line through the origin, described by the equation y = kx.

β–ΈHow do you find the constant of proportionality?

Divide one quantity by the other to get the unit rate, which is the constant k. If 3 kg cost 12 dollars, then k = 12 Γ· 3 = 4 dollars per kg. The Constant of Proportionality sub-skill here builds exactly this skill.

β–ΈHow is Grade 7 ratio work different from Grade 6?

Grade 6 introduces ratio language and unit rate; Grade 7 uses proportional relationships to reason further β€” identifying the constant of proportionality, writing y = kx equations, and solving multi-step percent problems. The Solving Proportions sub-skill steps up to finding an unknown value.

β–ΈCan I use these worksheets for percent, tax, and tip problems?

These sheets drill the underlying skills β€” solving proportions, scaling quantities, and the constant of proportionality β€” that make percent problems solvable. For dedicated percent, discount, and tax practice, use the Percentages topic, which is built for that.

β–ΈCan I make a version for a substitute teacher or a retest?

Yes. The shareable link reproduces the identical worksheet and answer key, so a substitute prints the exact sheet you planned. Press Shuffle instead for a fresh set at the same difficulty when you need a clean retest, and switch on the easy-read font if a student finds dense pages hard to track.
