The Census Bureau estimates that in 2020, 15 of the 50 states will have a Spanish-speaking majority. What percent of the states will have a Spanish-speaking majority?
The answer is: [C]: "30%" . _____________________________________________________ Explanation: _____________________________________________________ Note that: "%" ; or "percent" means "out of 100" ; or "divided by 100" . ______________________________________________________ Method 1)
15/50 = ?/ 100 ;
Look at the denominators:
50 * (what value?) = 100 ? ; → "100 ÷ 50 = 2" ;
→ 50 * 2 = 100 ;
So: "15/50 = (15*2)/(50*2) = "30/100" ; which is "30%" . ___________________________________________ Method 2: ___________________________________________ "15/50" = (15÷5) / (50÷5) = 3/10 ;
3/10 = (3*10) / (10*10) = 30/100 ; which is: "30%" . __________________________________________ Method 3: (slight variation of "Method 2" above): ___________________________________________ "15/50" = (15÷5) / (50÷5) = 3/10 ;
