An electrician needs 1 ¹/₄ rolls of electrical wire to wire each room in a house. How many rooms can he wire with 6 ¹/₄ of a roll of wire?

Quizplus · Accepted Answer

We can solve this problem by dividing the amount of wire he has (6 ¹/₄₎by the amount of wire required for each room (1 ¹/₄). Step 1: Convert 6 ¹/₄ and 1 ¹/₄ to improper fractions to make solving easier. Use the rule a ^b/_c = ^{(ac + b)}/_cto convert a mixed number to an improper fraction. In words, you multiply the denominator (bottom number) by the whole number and then add the numerator. Put that number over the denominator to create the improper fraction. 11ec0fda_98cc_5d93_a67f_a971867bfd07_NR0004_00 Step 2: Simplify. 6 x 4 + 1 = 25 and 1 x 4 + 1 = 5. 11ec0fda_98cc_5d94_a67f_e11b6c69bf45_NR0004_00 Step 3: 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. 11ec0fda_98cc_5d95_a67f_13777a554f49_NR0004_00 Step 4: Simplify. 25 x 4 = 100 and 4 x 5 = 20. 11ec0fda_98cc_5d96_a67f_e7bdd56ff40b_NR0004_00 Step 5: Reduce the fraction to its simplest form. 11ec0fda_98cc_5d97_a67f_5964799ac206_NR0004_00
