hey good morning this is Wednesday's review your third day of review and fractions three equivalent fractions for each fraction below so the rule for finding equivalent fractions easy way to do it is that if you multiply the top and the Bottom by the same number you're going to get an equivalent fraction you could also survived the top of the Bottom by the same number already reduced fractions top and the Bottom by the same number so for 2/3 I'm going to do the Stratford over here for 2/3 for my first equivalent fraction I'm going to multiply the top search numerator July 1st equivalent fraction is 4/6 times a different number on the top and the bottom to do times 5 are * 5 is 10 3 * 5 is equivalent fraction to 2/3 to 10:15 to 7 3 * 7 on the bottom is 21 so another equivalent fraction for 2/3 is 14 / 21 or not the only answers as long apply the top and the Bottom by the same number you're going to have equivalent fractions multiplying in my head and I'm going to write it out * 23 * 3 3 * 3 is 9 bottom times 3/5 * 301 is 915 now instead of multiplying by 3 I need a x another number for 3 * 4 is 12 5 * 4 is 20 one more time one more number to multiply 3/5 by 1000 * 6 * 6 is 18 equal or not equal between the pairs of fraction top and the bottom or X the same number if they were equal if they weren't what is 6 * 3 * 2/8 * next one four times what equals 12 before times three so then I say does 7 * 3 equal 20 5 * what equals 10 * 2 * 9 * 2 equal 30 not equal 35 lb 7 * 5 * 5 does not equal 40 and it does so these are Thomas you're adding and subtracting fractions to remember the big rule for adding and subtracting fractions that you cannot add or subtract fractions unless they have the same thing denominator so we can go ahead and add the numerator 3 + 3 + 6 is a nominator state which is a correct adding and subtracting fractions we were always reducing our answer so we look at 6 a.m. and say is there anything I can divide 6 and 85 and answers to I can do when I get 8 / 2 / is one which is reduced subtraction they already have the same numerator it's going to rain tonight I'm just going to subtract Panther Academy the answer to 3 divided top in the Bottom by 3 9 / 3 IS300
