Front 1

what are digits, and place values

Back 1

digits: 1-9 & 0

place values: ones, tens, hundreds, thousandths, etc

Front 2

when subtracting two numbers describe the concept of "regrouping"?

Back 2

when you go next door to the next place value to borrow and reduce that place value by 10 and add 10 to the current place value

Front 3

product=?

Back 3

multiplication

Front 4

define dividend, divisor, quotient, and remainder

Back 4

dividend: #being divided

divisor: # dividend is being divided by

quotient: answer to division problem

remainder: what's left and can't be divided

Front 5

where do decimals go in long division problems?

Back 5

directly above it, stays in the exact same place

Front 6

when adding and subtracting decimals what happens to the decimal points

Back 6

you must align the decimal points

Front 7

what to do when multiplying two decimals?

Back 7

multiply normally then count how many decimal place values each number is at, then add the two place values. so if one number is 1.5 and the other number is 2.6 then the final answer would have a decimal two places to the left

Front 8

describe 4 steps of division with decimals

Back 8

1. set up the division problem 2. move the decimal pt. in divisor until it's a whole #. 3. move decimal pt. in dividend the same number of spaces as was moved in the divisor. 4. divide normally

Front 9

define factor, LCD, common denominator, reciprocals

Back 9

factor: # that divides evenly into another #

LCD: smallest multiple that 2 numbers share

Common denominator: 2 or more fractions having the same denominator

reciprocals: pairs of numbers that equal 1 when multiplied together

Front 10

how to change an improper fraction into a mixed #

Back 10

divide normally, the numerator by the denominator

Front 11

how to add fractions?

Back 11

find a common denominator, and add the numerators

Front 12

how would you subtract fractions with unlike denominators

Back 12

find the least common denominator, what is done to the bottom must be done to the top, then subtract the numerators

Front 13

how do you multiply fractions?

Back 13

top x top, and bottom x bottom

Front 14

how to divide fractions

Back 14

flip the second fraction, use its reciprocal then multiply

Front 15

how do you change a mixed number into an improper fraction?

Back 15

multiply the denominator by the whole number then add the numerator. for the answer, the denominator stays the same, and the numerator is that new number you solved for

Front 16

how would you change fractions into decimals?

Back 16

use long division, denominator outside the house, numerator inside the house

Front 17

how would you change a decimal into a fraction? how would you change a decimal into a fraction when it's a whole number like 3.055

Back 17

look at the place value, so .25 as a fraction is 25/100 bc the 5 is in the hundredths place.

the 3 becomes a mixed number, and the 55 becomes the numerator, the 5 is in the thousandths place so 1000 is the denominator. the answer is 3(55/1000)

Front 18

define ratio and proportion

Back 18

ratio: relationship between two numbers

proportion: two ratios that have equal values

Front 19

how would you change a decimal into a ratio?

Back 19

change the decimal into a fraction, then turn the fraction into a ratio. the numerator is the first number and the denominator is the second number

Front 20

what to do when solving proportions

Back 20

rewrite proportions as fractions, cross multiply, then solve for X

Front 21

how would you change a decimal to a percent?

Back 21

move the decimal two places to the right

Front 22

how would you change a percent to a decimal?

Back 22

move the decimal two spaces to the left

Front 23

how would you change a fraction into a percent

Back 23

divide numerator by denominator

Front 24

what is 7 out of 8 expressed as a percent? how would you solve this?

Back 24

use the percent formula. so set up 7/8 as a fraction then %/100 as a fraction. and cross multiply. and solve for the %
