The history museum is less that 9 4/5 miles. 9/10 means that the 9 3/4 mile is broken up into 10 equal parts and the distance to the museum is only 9 of those parts. 9 3/4 (9.8) divided by 10 equals 98/100 (.98)
98/100 x 9 = 882/100 or 8.82
Justin's house is 8.82 miles from the museum.
X= a number
If 52 is 130% of a number, then we multiply the unknown number by 130%.
x * 130%= 52
convert % to decimal (130%÷100)
1.3x= 52
divide both sides by 1.3
x= 40
ANSWER: The unknown number is 40, so it is less than 52. We multiply the unknown number by 130% to equal 52.
