Unit D · Factors, Ratios & Proportions
From parts to proportion — where fraction sense becomes ratio thinking.
Six skills, one storyline: factors and multiples build the tools; GCF and LCM sharpen them; ratio, rate, proportion, and percent put them to work. Eighty questions, four sets, rising difficulty.
How long is this practice session?
When time runs out, the set ends automatically and you're scored only on the questions you answered.
