Libby Berkovitch: one million) four.nine + four/17 = four.ninety + zero.23 = five.thirteen two) one million/two + one million/two = two/two = one million three) four/nine + one million/three = four/nine + three/nine = 7/nine = zero.seventy seven four) one million/two - four/17 = nine/34 17/34 - eight/34 = nine/34 nine/34 = nine/34 ==> CORRECT five) five/6 - five/17 = zero.eighty three - zero.29 = zero.fifty four 6) one million/two - three/eleven = five.five/eleven - three/eleven = two.five/eleven = zero.227 7) five/7 - three/thirteen = zero.seventy one - zero.23 = zero.forty eight eight) one million/two x three/thirteen = three/26 (one million x three) / (two x thirteen) = three/26 three / 26 = three/26 ==> CORRECT nine) one million/two x four/eleven = (one million x four) / (two x eleven) = four / 22 = two/eleven 10) four/7 x five/19 = (four x five) / (7 x 19) = 20 / forty five = four/nine eleven) one million/two x five/12 = (one million x five) / (two x 12) = five / 24 ! 12) five/eight / (five/thirteen) = one million five/eight five/eight x thirteen/five = one million + five/eight (five x thirteen) / (eight x five) = eight/eight + five/eight sixty five / forty = thirteen/eight thirteen / eight = thirteen/eight ==> CORRECT thirteen) five/7 / (two/7) = five/7 x 7/two = (five x 7) / (7 x two) = 35 / 14 14) two/three / (one million/four) = two/three x four = eight / three 15) one million/two / (two/nine) = one million/two x nine/two = nine / (two x two) = nine / four In a few circumstances, while we now have a fragment it's higher if we write it as a decimal (comfortably through dividing the numerator with the denominator). But in a few circumstances additionally it is a higher proposal to paintings simplest with the numerators of the fractions (if they've the equal denominator). Also, take into account that once dividing fractions you're truthfully multiplying the fraction through the reciprocal of the opposite one. Example: two/nine divided t! hrough five/eight ==> two/nine / (five/eight) divided (/) thro! ugh five/eight ==> instances (x) eight/five (reciprocal of five/eight) two/nine / (five/eight) = two/nine x eight/five = (two x eight) / (nine x five) = sixteen / forty five NOTE: If the fraction can also be simplified, do it. In this situation sixteen and forty five can not be simplified however they may be able to be awarded as a decimal (sixteen/forty five = zero.35). Hope this helped and well success! :)...Show more
Benita Nancy: Ok, to rename the fractions using a common denominator, you need to make the fraction equal the same amount that it is already equal to but it needs to contain different numbers. The proportions are still the same though. So if you had a pizza that was split into four pieces and you took one away, you would have 3/4 left. If you put that piece of pizza back and cut the pizza into 8 pieces and then you took 2 away, you would be left with 6/8 of the pizza. 3/4 is equal to 6/8. So one way you could rename your fractions is by multiplying the! numerator (the top number) by the denomanator (the bottom number) both by 2 or any other number, as long as you multiply the top number by the same number you multiply the bottom number by. so 2/5 = 4/10 , 3/4 =6/8 I hope this helps =D...Show more
