Sarah is painting tiles for her art project. She has ⁸/₉ of a liter of paint remaining. Each tile requires ¹/₁₈ of a liter of paint. How many tiles can she paint?

Quizplus · Accepted Answer

We can solve this problem by dividing the remaining paint (⁸/₉ of a liter) by the amount needed for each tile (¹/₁₈). Step 1: Use this rule to divide fractions: a ÷ ^b/_c = a × ^c/_b All the rule above states is: to divide fractions, flip the second fraction and multiply. Note that any whole number written as a fraction is that number over 1, so we can express 18 as a fraction as ¹⁸/₁. 11ec0fda_98d7_0c58_a67f_97a15bfdc554_NR0004_00 Step 2: Simplify. 8 x 18 = 144 and 9 x 1 = 9. 11ec0fda_98d7_0c59_a67f_c79243f97162_NR0004_00 Step 3: Reduce the fraction to its simplest form. The numerator (144) and denominator (9) are both divisible by 9. 144 ÷ 9 = 16 9 ÷ 9 = 1 So, our reduced fraction would be ¹⁶⁄₁ 11ec0fda_98d7_0c5a_a67f_b7f1a8752c57_NR0004_00
