is the park on the map?
Answer: 2 times 100 = 200 divide 200 by 400 = 1/2
●● On a map 1/2 in represents 4 miles if two cities are 18 inches apart
on the map what is the actual distance between them?
Answer: 8 miles = 1 inch 8 miles times 18 inches = 144
,●● If a certain recipe takes 1 1/4 c sugar and 4 c milk how much milk

●● Vonna scored 48 goals in her soccer practice. If her success to failure
rate was 3:2 how many times did she attempt a goal?

by the number of successes 96/3 = 32 then add total goals kicked 32 +48
= 80
●● Subtract when dividing
Answer: Square roots top and bottom higher number on top, lower
number on bottom
●● 2 1/2 is to 6 as x is to 18
Answer: 2 1/2 x 18 = 45 then divide by 6 = 7 1/2
●● 6 over 7 = 3x over 42
Answer: 7x3x = 21x then 6x42 = 252 then divide by 21 = 12
●● rational number
Answer: any number that can be written as a fraction
, ●● irrational numbers
Answer: numbers that cannot be expressed in the form a/b, where a and
b are integers and b =0.
●● Intergers
Answer: whole numbers and their opposites
●● terminating decimal
Answer: a decimal whose digits end and the prime factorization of the
denominator contains no primes other then 2 or 5
●● Decimals from Greatest to Least
Answer: write them all out in a row add 0's to make them all have the
same decimal places, put them in order by decimal places. Negatives are
backwards
●● Fraction to a Decimal
Answer: Use F-D key on the calculator
●● 3.36 with line over the 36
Answer: convert to 336.36 then subtract 3.36 from that and place it over
99 so = 333 over 99, then reduce to lowest terms
