Card 7Finding Missing Term in Proportion

The numbers 8, x, 9, and 36 are in proportion. Find x.

Answer

Since they are in proportion: 8 : x = 9 : 36 Cross-multiply: 8 × 36 = 9 × x → 288 = 9x x = 288 ÷ 9 = 32 Answer: x = 32…

Card 8Ratio in Mixtures

The ratio of copper to zinc in an alloy is 9 : 8. If zinc weighs 9.6 kg, find copper weight.

Answer

Let copper = 9x, zinc = 8x Given: 8x = 9.6 → x = 9.6 ÷ 8 = 1.2 Copper = 9 × 1.2 = 10.8 kg Answer: 10.8 kg…
